My little dog is coughing often and sometimes seems to struggle to breathe.

What is tracheal collapse?

Tracheal collapse is a common cause of coughing and airway obstruction in dogs. The trachea, which is also known as the “windpipe”, provides the air supply from the outside to the lungs. The trachea can be thought of as resembling a vacuum cleaner pipe. It is a flexible but firm tube that is reinforced by strong cartilage rings. These rings are not complete but rather “c-shaped”, with the open end of the “c” facing to the inside of the neck with a ligament attaching from the one end of the C to the other. Sometimes these cartilage rings weaken and cannot hold their shape causing the trachea to narrow or even close, making it more difficult for air to pass through.

Which dogs are prone to tracheal collapse?

The small and toy breed dogs are most commonly affected by this condition.  Yorkshire terriers, Toy Pomeranians, Poodles and Chihuahuas are some of the most commonly affected breeds. Young dogs can be affected but the condition is more commonly seen in middle-aged to older patients. These dogs are often overweight and living in a household that has smokers often exacerbates the condition.

What are the signs of tracheal collapse?

  • The dog often has a characteristic “goose honking” cough.
  • The dog may cough when picked up or pulled on a collar.
  • Some dogs may have difficulty breathing and some turn blue when excited.
  • There is usually a degree of exercise intolerance and a wheezy noise may be heard when the animal breathes in.
  • The cough and other signs are often worsened with excitement, eating, drinking, tracheal irritants such as smoke, dust or pollution, obesity, exercise and hot and humid weather.

Diagnosing tracheal collapse

The clinical signs and breed of dog make a diagnosis of tracheal collapse highly likely. X-rays can be helpful in making a diagnosis but the collapse of the trachea is often dynamic so may not be seen all the time. Fluoroscopy is a moving x-ray and is beneficial in that the trachea can be visualised over a short period of time. Unfortunately, fluoroscopy is usually only available at veterinary teaching hospitals and some veterinary referral centres. Using a scope is the only way one can see what is happening within the trachea and may also be useful as swabs and cultures can be taken to make sure there is not a secondary infection present concurrently.

Can tracheal collapse be confused with other conditions?

Tracheal collapse can definitely be confused with other upper respiratory tract conditions of which the most common one in toy breeds is arguably reverse sneeze. Kennel cough, an infectious viral condition of the upper respiratory tract is another. Allergies are another common cause of upper respiratory tract conditions. A foreign body like a grass awn which gets stuck somewhere in the upper or lower respiratory tract is another possibility. To differentiate which condition your dog may be suffering with will most likely require a thorough clinical examination and diagnostic workup by the vet.  

Can tracheal collapse be cured?

Unfortunately, tracheal collapse cannot be cured but it can be managed relatively successfully. Medical management includes medication to suppress the cough, reduce airway inflammation and spasms, and reduce anxiety. Weight loss is probably the most important aspect of management in overweight pets as obesity greatly exacerbates the condition.

In some cases, surgery may be an option to help support the trachea. It is a specialist procedure and an animal will still need to be managed medically afterwards. Surgery does come with its own risk so it is important to speak to an experienced surgeon before travelling down this route. It is also important to remember that not all animals will be ideal candidates.

At present, there is no known way to prevent tracheal collapse but maintaining an ideal weight and reducing exposure to airway irritants such as smoke have been found to help. Patients may be managed relatively efficiently with medical management and it is estimated that more than two-thirds of dogs will show some improvement. About three-quarters of dogs will improve with surgical treatment but the surgery does also carry its own risks. Older dogs may also have laryngeal or bronchial disease. This also comes with complications and does reduce the long-term prognosis for management.  Weight management and control of the cough is vital for a good outcome and it is important to remember that medical management is still instrumental even after surgical treatment. 

There is a strong school of thought that suggests tracheal collapse may be inheritable because it is related to the shape and confirmation of the trachea. Just like you may find some dogs have longer legs and some have shorter legs, so some of the toy breeds may have narrower tracheas than others. It would certainly stand you in good stead to do some proper research before buying a highly pedigreed toy breed of dog.

If you are not sure if your dog may be suffering with tracheal collapse, visit the vet and have a proper exam done. It may just improve the quality of life of your best friend.

How that cute puppy came to cost you R 150 000

We are approaching that time of year when people are considering what to gift people for Christmas and as is often the case, a cute puppy or kitten comes to mind. Many people do the noble thing of going to a shelter or a welfare organisation to adopt a puppy or kitten for a mere R 650. What they fail to realise is that that cute puppy or kitten is not just a R 650 worth purchase but more likely a R 65 000.00 one, or in some cases up to a R 150 000. How is that possible or what do you mean, you might ask?

Primary healthcare

For starters, that cute puppy or kitten will need at least three- to four initial vaccinations to protect them from some fatal diseases. To that, you can add a required dose of monthly deworming, to ensure that the lifecycle of the worms is properly broken. The cost of this exercise could easily set you back anything from R 2000 to R 3000.

Depending on the season of the year you acquire your puppy or kitten, they are going to need regular (at least monthly) tick and flea treatments for at least three to six months, in succession. Depending on the products you use; and the size of your dog or cat, this exercise will likely cost you anywhere between R 500 and R 1200.

Pet Accessories

Recommended accessories when adopting a new puppy or kitten include a bed or basket, a sandbox for kitties, a collar and lead for your dogs, brushes, bowls, and toys. There goes another R 2000 to R 10 000. Indoor cats will need cat litter for the rest of their lives. The cost over your cat’s lifespan (20 years) will likely be in the order of R 18 000.00. Puppies that are kept indoors will need training pads for the first three to six months; these can cost you about R 1300.

Puppy training is a crucial part of socialising and integrating your dog into your family and society in general. The cost of a training program, including travel to and from classes once a week, will most likely set you back between R 5000 and R 8000.

Sterilisation

When your pup or kitten is six months old, they need to be spayed or neutered. In female animals, this is a full ovariohysterectomy and this procedure is heavily subsidised by most vets, assisting the public in preventing unwanted pregnancies. The true cost of this operation, which is a full-blown surgical procedure done under general anaesthesia and inside a sterile operating theatre, is in the order of R 4000 to R 4500. Most vets, however, charge somewhere between R 1200 to R 2500 for this procedure.

Food

By far the most expensive items for your puppy or kitten throughout their lives will be their food. Here, there is a range of prices depending on the quality of food you feed. The general principle here is that the more expensive the food is, the better the quality and usually the better condition your pet will be in and the longer they will live. Size really matters and the cost of a super premium diet for a small breed dog weighing 5 kg or less, will be in the order of R 80 000 over its lifetime (15 years) whereas the cost per day for a large breed dog 30 kg will be R 190 000 over its lifetime (12 years). The cost of feeding a premium diet to a small breed dog weighing 5 kg or less, will be in the order of R 53 000 over its lifetime (15 years) whereas the cost per day, for a large breed dog weighing 30 kg, will be R 180 000. Feeding a poor quality pet food is going to cost less, but your animal may, as a result, not be in optimal health condition and can be prone to diseases.

Annual Wellness exams

Dogs and cats age on average the equivalent of seven human years for every calendar year. When your puppy or kitten grows into a mature dog or cat, they will need to see the vet for an annual health and wellness exam and vaccination if required. This visit is the equivalent of seeing your doctor every seven years. Most people, especially ageing people, need to see their doctor more frequently. The same principle of frequent doctor’s visits applies to your pets too and these annual visits to the vet will set you back roughly R 15 000 over the lifetime of a pet with a 15-year lifespan.

Veterinary care

Veterinary expenses remain a significant contributor to the total expenditure on a pet. You may be lucky and have an extremely healthy pet that may only need to see the vet once a year for their annual wellness exam.

If however, you are unlucky and have a pet that sustains a severe injury that needs intensive veterinary intervention and care, like bite wounds, being hit by a car or tearing a knee ligament, the cost of treatment may easily set you back anywhere between R 10 000 and R 30 000.

If your pet develops a condition that either needs ongoing treatment or a therapeutic diet, the cost may be anywhere between R 5000 and R 50 000. Veterinary care, like human medical care, is not cheap. Vets study for six years and veterinary medicine happens to be one of the most expensive veterinary courses available.

Most veterinary hospitals or clinics have to have the same equipment you will find in most human hospitals like X-ray machines, fully equipped operating theatres, laboratories, dentistry suites and special care equipment and facilities. The cost of setting up and equipping a veterinary hospital can easily be between R 1 mil to R 2 mil, excluding the cost of the physical property.

Compared to what humans pay in private medical hospitals, the cost of having a pet admitted to a private veterinary hospital is minuscule. However, most people still don’t have medical aid for their pets like they do for themselves, which means that should disaster strike and intensive veterinary care is needed, all of those costs need to be paid from discretionary, “leftover” income, something which is indeed almost non-existent for most people.

Dental care

The recommended norm for humans to see a dentist is every six months. An annual wellness exam for your dog or cat will be the equivalent of a seven-year gap to see the doctor or dentist, in the case of humans.

As animals get older, most of them develop plaque that calcifies, forming calculi on the teeth. The only way to treat this effectively, other than preventing it by brushing your pet’s teeth daily, is to have it removed by ultrasonic dental descaling under a full general anaesthetic. The cost of this procedure is in the order of R 3000 to R 4000. Many vets also subsidise this procedure to make it more affordable for pet owners to have their pets’ teeth cleaned.

Summary

For the sake of this article, we have worked on an annual inflation rate of 5%. As rates fluctuate, so do prices, and it may either cost you significantly more to own a pet in times of high inflation or less in times of lower inflation. Either way, it should be clear to anyone wanting to adopt a pet to remember that it is not a R 650 transaction but more likely a R 150 000 transaction.

My cat is eating like crazy and not picking up weight

What is hyperthyroidism?

Hyperthyroidism is a condition that arises from an excessive production and secretion of active thyroid hormones by an abnormally functioning thyroid gland. First recognised in the late 1970’s, the frequency of diagnosis has escalated dramatically – currently it is the most common endocrine (hormone system) disease in cats and also one of the more frequently diagnosed disorders in the veterinary field. The condition is estimated to affect 1 in 300 cats.

What causes hyperthyroidism?

Despite several studies, the exact cause of the disease remains unknown. Recent studies have found that there is no breed association with risk. Other studies have found cats fed mostly tinned cat food, especially fish or liver and giblet flavour, and cats using cat litter are at increased risk.

Soybeans have also been implicated as a potential culprit as it is used as a protein source in some commercial cat foods. Furthermore, the thyroid gland contains more selenium than any other tissue, which suggests this trace element may play an important role.

Which cats are affected?

The disease typically affects middle-aged to older cats, with an average age of onset at 12-13 years.  Rarely can it affect cats as young as 4 years of age. There is no breed or gender predilection.

What are the clinical signs of hyperthyroidism?

Thyroid hormones are involved in a wide variety of functions in the body, including the regulation of heat production, metabolism and interaction with the nervous system. Therefore almost any organ system can be affected and subsequently a wide variety of clinical signs are possible.

Typically the signs start out very subtle and slowly progress, causing most owners to not notice them for several months. Some owners may also put these signs down to the normal “ageing” process.

The most common clinical sign is weight loss, despite a voracious appetite. Affected cats may seem constantly hungry and “finicky eaters” stop being “finicky”, eating everything that is offered to them or that they can get to.

Affected cats often gobble down their own food before going on to eat all the other pets in the household’s food as well; they may even try to steal your food off your plate if given the chance. Remember that cats are a lot smaller than us humans – losing for example 500g is not significant weight loss for a human but for a cat it’s about 10-20% of their total body weight and definitely a cause for concern.

Affected cats also become hyperactive – they may seem restless, anxious and irritable, constantly moving or even pacing, sleeping for short periods only and wakening easily. When brought to the vet these cats typically won’t sit for the vet to examine them and become aggressive when attempts are made to restrain them.

Affected cats are also weak and tire very quickly – you may notice it can’t jump as well as it used to. They also can’t cope with stress – short car rides, bathing, boarding or vet visits may weaken them severely or even cause them to collapse.

The digestive system may also be affected, causing vomiting, soft, bulky, stinky stools and sometimes even diarrhoea.

How is hyperthyroidism diagnosed?

Hyperthyroidism can cause a wide variety of clinical signs, many of which can be caused by several other disease processes as well. Vets may perform several tests on your cat to rule out, amongst others, diabetes, kidney disease, heart disease, pancreatic disease and cancer. These tests may include blood tests, urine analysis, X-rays and even an electrocardiogram or ECG.

The diagnosis is confirmed by measuring the amount of thyroid hormone circulating in the cat’s blood.   Affected cats’ values may be up to 19 times more than the top normal value.

It is worth noting that up to 10% of affected cats may have borderline or even normal levels of thyroid hormone. These cats are either mildly affected or are suffering from another non related concurrent illness which is suppressing the thyroid levels. Therefore, the vet may decide that a single measurement is not enough to either rule in or – out thyroid disease and may recommend additional tests.

How is hyperthyroidism in cats treated?

Affected cats are generally started on anti-thyroid medication to stop the excessive secretion of thyroid hormones. The medication can be given between one and three times a day. The vet will typically start on a certain dose and repeat the thyroid hormone levels by doing a blood test after two weeks from commencing treatment.

Depending on the result, the dose may be increased or decreased and the blood tests repeated again after two weeks. This process will continue until the thyroid hormone levels return to the normal range. Once this is achieved, thyroid blood levels will need to be retested every 3 to 6 months or whenever otherwise indicated. 

The success of the therapy will mostly depend on you, the owner, as you will be the one tasked with administering the medication. It is important that you stick to the prescribed dosage and return to the vet for scheduled follow-ups or whenever your cat shows any signs of illness.

Cats are notoriously hard to pill! If you find it impossible to administer the medication, let the vet know as soon as possible – we will be happy to show you how to give the medication or help you come up with an alternative.

In some cases the vet may opt to surgically remove either one or both of the thyroid glands. Generally, the procedure cures the disease, but there is always a risk of it recurring – therefor the vet may want to monitor the progression of the disease every 6 to 12 months; if it recurs the cat will have to go onto medication again.

The vet may also recommend a diet change as there are therapeutic diets which have been specifically developed for this condition.

The last option is destruction of the thyroid gland via radioactive iodine, which is currently not readily available in South Africa.

What’s the connection between hyperthyroidism and kidney disease?

Hyperthyroid cats are predisposed to kidney disease due to the effects of the higher metabolism on the kidneys. Conversely, the higher metabolism also masks the signs of kidney failure. Consequently these cats often start showing signs of kidney failure once their thyroid condition is brought under control.

The vet may decide to monitor you cat’s kidney enzyme levels along with the thyroid levels in order to diagnose kidney failure as early as possible.

What’s the connection between hyperthyroidism and heart disease?

Hyperthyroid cats are prone to developing heart murmurs, abnormally fast heart rates and abnormal heart rhythms. The vet may notice these abnormalities when listening to the heart with a stethoscope.

The excessive amount of circulating thyroid hormone makes the heart work harder than normal, which is further worsened by having to keep up with the cat’s higher metabolic rate. Over time the heart muscle starts thickening and/or the heart chambers start dilating to increase their size in an attempt to cope with the increased workload.

Congestive heart failure sets in eventually when the heart cannot keep up anymore fluids starts building up in the lungs and/or the abdomen.

If the vet suspects heart disease, he or she may decide to investigate further with ECGs, ultrasonic heart scans and X-rays. Depending on the findings, the cat may have to go onto heart medication as well.

What is the prognosis for hyperthyroidism in my cat?

The prognosis will depend on the cat’s physical condition, age, and whether other diseases are present. When treated, the average survival rate is 2 years and the quality of life is acceptable.

My Dog is Pregnant

Is my dog pregnant?

In the days before high walls and fences in South Africa, it was quite common for dogs to roam around freely in cities and towns; and it was not uncommon to discover out of the blue, that your female dog at home may be pregnant without you knowing how she fell pregnant.

Having said that, in those days most people who had an un-spayed (unsterilized) bitch at home, would have known very well that she was “in season” or “on heat”, which is the time the female dog is ready to ovulate and mate, because the whole neighbourhoods’ male dogs would have been howling at the door for “a piece of the action”.

Male dogs can smell bitches in heat up to 3 kilometres away and not spaying a female dog you do not want to breed with, can leave intact male dogs in agony because of nature’s drive to mate when there is a female in season. Some of this is still happening in informal settlements in South Africa in this day and age and therefore there is strong drive from welfare and community-driven organisations like the Community Veterinary Clinics of the South African Veterinary Association, to sterilise as many pets as possible and prevent unwanted litters.

These days, most people who do not sterilise their pets, because they are planning to breed with them, will know exactly when their bitches are on heat and will have full knowledge of when the mating takes place and when the puppies can be expected.

Bitches are usually on heat for 10 to 14 days. In the first week, they are very attractive to male dogs but, will not allow mating and even turn around and try to bite male dogs who try to mate with them. The second week of being on heat they are as attractive to male dogs as the first and will readily allow a male dog to mate with them and even seek out a male to mate with during this time period.

It is quite possible for a bitch to mate several times in the second week of their heat season. It is also possible for a litter of puppies to have different fathers. The male dog’s sperm can stay active inside the female dog’s genital tract for up to 7 days after mating.  

How long is pregnancy in dogs?

Dogs have a gestation period or said in another way, dogs are on average pregnant for 63 days.  

How do I know my dog is pregnant or how far my dog is pregnant?

If one is not sure whether your female dog was covered (or mated) with a male dog when she was on heat, there are other ways to confirm the pregnancy. To diagnose the pregnancy, an ultrasound can be performed from the 25th day after breeding. Alternatively, blood progesterone levels can be measured from the 34th day onwards. The average duration of pregnancy is 63-64 days from the date of breeding but can range from 56 to 72 days.

At around the Day 45, the vet may recommend that you bring your bitch for a check-up and X-rays, to determine how many puppies she is carrying. An ultrasound is not a reliable way to determine how many puppies your bitch is carrying and the fail-safe method to determine the number of puppies in a pregnancy, is through  X-ray.

What happens before my dog gives birth?

As the pregnancy progresses, you will notice that your bitch will gradually start eating more than usual and will start eating a lot more once the puppies are born and nursing from her. Do make provision for the requirement of more food for her but, try to feed her smaller meals more often rather, than one or two large meals per day. A small or medium breed (not large breed) puppy food from a reputable brand will provide her with all the nutrients she needs during this time. Do not give her any supplements without discussing it with a vet first. Supplementing with, for example, calcium or vitamin D can actually increase the risk of complications and is usually not recommended.

Two weeks before her estimated due date, purchase a thermometer from any pharmacy and start taking her rectal temperature at the same time every day; ideally twice a day. The tip of the thermometer can be lubricated with K-Y jelly or similar inert lubricant before being inserted into the rear end. A temperature of between 37.5°C and 39.5°C is normal for a dog. Yes, dogs are on average 1.5 °C  warmer than humans. Typically the bitch’s temperature will suddenly drop by 1 to 3°C, 12 to 24 hours before she goes into labour.

Whelping – what is normal?

Most dogs are able to give birth naturally without any assistance or complications but it is useful to know what to expect and when intervention is needed.

When the whelping process begins, the bitch will first enter stage 1 of labour, where her cervix begins to dilate to allow the puppies to pass through the birth canal. She will appear restless and uncomfortable – pacing, shivering, panting and whining. She will probably not eat and may even vomit. She may also search for a quiet, secluded spot and create a nest to whelp in. This stage can last anything from 3 to 24 hours.

Thereafter the bitch will enter stage 2 of labour, where the placental sacs tear and release straw-coloured fluid (her “water breaks”) and uterine contractions begin. Each puppy has its own set of foetal membranes. The puppies are delivered, on average, every 30 to 60 minutes. The bitch may also “rest” between puppies for to 4 to 6 hours, during which no contractions occur. Once a puppy is delivered, its mother will bite off its umbilical cord and lick it clean – it is important that she is allowed to do this as it stimulates the puppy’s breathing and helps the mother to bond with the puppy and produce milk.

If the mother doesn’t perform these crucial steps within 3 minutes you may have to intervene and do it yourself. Use some clean thread to tie a tight knot around the umbilical cord approximately 2.5cm away from the puppy. Use a clean pair of scissors to cut the umbilical cord about 1cm away from the knot towards the bitch’s end. Clear all the membranes and fluid away from the puppy’s face, nose and mouth and rub its body vigorously with a soft, dry towel to stimulate breathing. Check that the puppy is alive by feeling for a heartbeat. Place your index finger (not your thumb) behind the puppy’s elbow for a few moments – if it is alive you will feel the heartbeat against your finger. If the puppy has a heartbeat but isn’t breathing, be patient, it may take up to 10 minutes to start breathing. If you need to help more than one puppy in this way, use a separate clean, dry, soft towel for each puppy. The puppies are very slippery when born and using a wet towel will make them even more slippery – you don’t want a puppy slipping out of your hands and falling.

The mother usually eats the afterbirth and this behaviour is normal, so do not interfere with this process or try and deter her from eating it.

Stage 3 starts once the puppy is delivered and ends when its foetal membranes are expelled. The bitch will alternate between stage 2 and 3 when there is more than one puppy.

How involved do I need to be in the whelping process?

It is important to understand that a bitch can interrupt the whelping process if she is frightened, nervous or disturbed. You will thus need to provide her with a quiet, secluded spot in which to whelp and keep disturbances to a minimum.

Check on her every few minutes and only disturb her when absolutely necessary. If either you or the bitch are generally nervous or anxious and you are worried that it will interfere with the whelping process, contact the vet and discuss it with us. In some instances it might be better for everyone to have the bitch hospitalised and the process monitored by professionals.

The puppies should be left with their mother at all times and handled as little as possible. Newborn puppies are very cute and the temptation to cuddle them is often very high, but handling them too much will affect the bonding process with their mother negatively.

When should you call the vet?

Phone your vet as soon as possible when you notice any of the following:

  • 20 to 30 minutes of active contractions but no puppy is delivered
  • More than 4 hours pass since the birth of the last puppy and you suspect or know that there are more
  • No puppies have been delivered 24 to 36 hours after the rectal temperature has dropped
  • The bitch cries and licks or bites at her rear end during whelping
  • The bitch fails to enter stage 2 of labour after 8 to 12 hours of being in stage 1
  • The pregnancy progresses beyond the due date – beyond 70-72 days from the first breeding.
  • No puppies are born 2 hours after lochia or water-like discharges were first seen (see below)

Discharges of different colours– what is normal and when should you worry?

Greenish, with or without small amounts of blood: As the bitch enters stage 2, the uterus (womb) and the placenta surrounding the foetus separate from each other to allow the foetus to be born and the placenta to be expelled. This causes the greenish discharge, called lochia, and is normal.

Watery or egg white-like: Indicates that the bitch is starting to give birth. You may even see a water-filled bubble or balloon protruding from the vulva. These are the fluids that surrounded the foetus during its development and are normal.

Red: It is normal for the lochia to contain small amounts of blood. If you think that there is a lot of blood or are worried about anything, rather phone the vet and discuss it with us. Once whelping is completed, the bitch may have a bloody discharge for up to 6 weeks. This is due to the uterus involuting i.e. reconstructing and shrinking back to its pre-pregnancy size and state.

The bitch should have a normal temperature and not be showing any signs of illness during the time – if this is not the case she needs to be examined by a vet as soon as possible.

Stinky, yellowish-white or brown: The discharge contains pus, which indicates there is an infection in either the uterus or vagina. This is not normal and the bitch should be brought in to the vet for examination as soon as possible.

The birth of new puppies is a wonderful experience to go through and with the correct information at hand, you will be able to know when to assist your bitch or when to just leave her and let nature take its course.

My Collie is bumping into things and seems to have difficulty with its eye sight

What is Collie eye anomaly?

Collie Eye Anomaly is an inherited condition affecting both eyes of many different Collie type breeds of dogs. Interesting to note, that not only Collie breeds are affected but also some other breeds. Affected breeds include Rough and Smooth Collies, the Shetland Sheepdog, the Australian Shepherd, the Border Collie, the Lancashire Heeler, and the Nova Scotia Duck Tolling Retriever. 

The region of the eye affected by this genetic condition is called the choroid. The choroid is the layers of blood vessels and pigment between the sensory membrane that lines the inner surface of the back of the eyeball (the retina) and the outer white covering of the eye (the sclera). The locations of all the parts being described can be seen in the image below. 

The primary lesion is typically the underdevelopment of the choroid called hypoplasia, which results in the appearance of a pale spot on the back surface of the eye when looking through the pupil. More severe consequences may occur such as retinal detachment or bleeding in the eye, both of which may lead to blindness. The back part of the eye where the main nerve that runs from the brain the eye comes into the eye is called the optic disc. With Collie Eye Anomaly one will often find small areas of indentations next to the optic disc. These indentations look like holes in the structure of the eye and are also described as colobomas. The degree to which an individual animal may be affected varies considerably, from very mild, to severe enough that eyesight may be lost completely. The lesions are not progressive and normally do not worsen over time. Mildly affected dogs will just have the pale spot seen on the side of the optic disc. There will be no impact on the dog’s ability to see and the pale spots may be seen in very young puppies and not in adults. The choroidal blood vessels may be reduced in number and abnormal in shape. Up to 25% of dogs that are severely affected will have severe complications that result in significant vision loss. These include the retinal detachment (loosening of the membrane at the back of the eye), bleeding (ocular haemorrhage) and colobomas. This can happen in these severely affected dogs before two years of age and the severity in both eyes may differ. It is very rare for only one eye to be affected by this condition Although this condition does affect vision, it is fairly rare for a dog to be completely blind in both eyes.

How does a dog get Collie Eye Anomaly?

Collie Eye Anomaly is a fairly common condition in affected breeds that has its roots in breeding with affected animals who have not been identified as carriers of the genetic defect responsible. The single most important fact to remember is that Collie Eye Anomaly is genetic and all affected dogs can pass the disorder on to their offspring. It is therefore essential that regardless of the severity of the condition in any individual dog, that they should not be used for breeding. All dogs from affected breeds should be clinically examined and genetically tested before breeding to avoid this unwanted condition to be passed onto their offspring. 

How is Collie Eye Anomaly diagnosed?

Diagnosis of this condition is generally confirmed through an ophthalmic (eye) examination by a veterinary eye specialist (veterinary ophthalmologist). The back of the eye is examined through an ophthalmoscope and an area of pallor is identified. This may be done from as early as 5 – 8 weeks of age. As the puppy grows, the retina becomes more pigmented and this may mask the changes in the choroid which means that the eye exam at an older age may appear to be normal, yet the dog still has the condition and is still a carrier of the gene which causes this condition. It is for this reason that all puppies must be examined at a young age, especially if they may be used for breeding later in life. Another fact to understand is that even a mildly affected dog may produce offspring that can be severely affected. 

There is also a genetic test available that may be used by vets and breeders to avoid transmission of the disease to the next generation.

How does Collie Eye Anomaly spread?

Having established that Collie Eye Anomaly is a genetic condition where the structure of gene changes (known as a mutation), fortunately, the gene mutation responsible for the defect has been identified. This mutation is found on chromosome 37 on dogs. This is a recessive mutation. A recessive gene is a gene that can be masked by a dominant gene. To have a trait that is expressed by a recessive gene, both parents must pass on the mutated chromosome for the condition to be clinically apparent. 

How is Collie Eye Anomaly treated?

Unfortunately, there is no treatment for Collie Eye Anomaly. The best way to prevent this in our dogs is to take part in conscientious responsible breeding, testing all animal from a young age and only breeding with dogs that are negative for both clinical signs and absent genetic mutation. This is our only weapon in the battle against a condition that can be very debilitating to affected pets and it is our responsibility to ensure we aim to breed for the health of our dogs above any other trait that may be deemed desirable.

What is the prognosis if my dog is diagnosed with Collie Eye Anomaly?

The prognosis of Collie Eye Anomaly depends on the extent to which the individual dog is affected. The condition does not normally progress however in early severe cases the indentations (colobomas) around the optic disc where the eye nerve enters the eye from the brain may lead to retinal detachment, which will make the condition severe at an early stage and lead to complete blindness which may lead to euthanasia. If the condition is not so severe and there is partial loss of sight, the dog will learn to cope with the partial loss of sight and will be able to live a good quality life. 

Conclusion

It is very important to have any Collie type breed dogs tested for this Collie Eye Anomaly at a very young age (between 6 and 8 weeks of age), so if you do get a puppy that falls in this category of breeds, speak to the vet to set up an appointment with a veterinary eye specialist, to have the test done. A more ideal situation would be to request a certificate from the breeder that you obtain your puppy from, issued by a veterinary ophthalmologist, confirming that the necessary examination and tests have been performed and that the puppy you are obtaining does not have Collie Eye Anomaly.

From Kitten to Cat

Tiny fuzz-balls of cuteness – the perfect description for every kitten. We cannot resist them creeping into our hearts. 

You have brought your new kitten home and realise it is dependent on you for its every need. For the kitten, the world is huge, brand new and can be a bit scary. Every sight, sound, smell, person and animal are a new experience. These first experiences are likely to influence their future behaviour.

Kittens learn first from imitating their mothers, then through trial and error. The bulk of their learning occurs from birth to six months, although learning and training is still possible as an adult.

The communication behaviours, specific to felines, are established early on in life. This is known as the socialisation period which starts from about 2 weeks after birth until about 16 weeks of age. 

During this time, it is important to provide the kitten with an ‘enriched environment’. In other words, they need different stimuli that will arouse their senses and spark their intelligence. 

Expose your kitten to different noises, textures and objects, much as you would a newborn human baby; and interact with them as much as you can. 

Good early socialisation leads to friendly, well-adjusted adult cats which are less likely to be scared. Sadly, without positive early experiences, cats can become nervous, which often leads to behavioural problems. 

It is good to choose a kitten that has had good socialisation from the breeder or owner of the litter. The kitten would normally still be at home with its mother and should have mixed with other people and pets, seen everyday sights and heard normal household sounds at the breeder- or owner’s home.

The Life of a Kitten

Let’s go through the life of a kitten from birth to 18 months.

Birth to 2 weeks: Your kitten learns to orient toward sound. Their eyes begin to open, they are usually open by 2 to 3 weeks of age.

2 to 7 weeks: Your kitten becomes social. By the third week, their sense of smell is well-developed, and your kitten can see well enough to find its mother. 

Cats can only detect the colours blue and green with certainty but require six times less light to see than humans. This is why they move excellently at night because they distinguish depth better than humans in the dark. 

Cats’ noses can detect a single molecule of odour whereas humans need several hundred. This makes for an extremely sensitive sense of smell. By the fourth week, their sense of smell is fully mature and their sense of hearing is well-developed. 

Feline ears can detect minute changes in frequency and tone making this an extra sensitive sense as well. Your kitten will learn to differentiate your voice from any other, adding to the bond between owner and pet. The kitten starts to interact with littermates and can walk fairly well. The teeth start to come in. 

By the fifth week, eyesight is well developed, and kitten can right itself, run, place its feet precisely, avoid obstacles, stalk and pounce and catch “prey” with its eyes. Kitten starts to groom itself and others. 

By the sixth and seventh weeks, kitten begins to develop different sleeping patterns, motor skills and social interaction abilities. Kittens are usually weaned at eight to nine weeks, but they may continue to suckle for comfort as their mother gradually leaves them for longer periods. 

Now is a good time to expose the kittens to different textured food to prevent them becoming fussy eaters. Orphaned kittens, or those weaned too soon, are more likely to exhibit inappropriate suckling behaviours later in life, such as sucking on blankets, pillows or your arm.

Ideally, kittens should stay with their littermates or other “role-model” cats for at least 12 weeks but it is safe to take them away from their mother by eight to nine weeks of age.

7 to 14 weeks: This is the age when your kitten will play the most. Social and object play increases kitten’s physical coordination and social skills. Most learning is by observation, preferably of their mother’s behaviour. Social play includes belly-ups, hugging, ambushing and licking. 

Object play includes scooping, tossing, pawing, mouthing and holding. Combined social/object play includes tail chasing, pouncing, leaping and dancing. 

Cats are generally curious creatures and quickly learn that food comes from refrigerators or countertops. Now is a good time to teach the kitten not to jump up. A stern “no” accompanied with a sharp sound like clapping will teach your kitten that this is unacceptable behaviour. 

It is difficult for felines to differentiate between which tables they are or aren’t allowed on to. For this reason, it should be an “all or nothing” rule. Remember to not hit your kitten as this may cause fear in your pet and lead to unwanted or aggressive behaviours. 

Toys come in handy at this stage of life. Any toy that encourages chasing and hunting-type behaviour is beneficial. It need not be expensive but can be as simple as a piece of paper folded in a block, tied to a string and dragged on the floor. 

Scratching, or ‘claw conditioning’ is a natural part of cat behaviour. It keeps their claws healthy and leaves scent marks. Try a scratching post for your cat to help prevent damage to your furniture or carpets. Ensure it's stable and tall enough for your cat to exercise at full body stretch.

3 to 6 months: Your kitten starts ranking the household and is most influenced by her ”tribe”, which may now include playmates of other species. 

Kitten begins to see and use ranking (dominance or submission) within the household, including humans. Your kitten will identify your home as its territory and will organise its life around this area. 

Kittens tend to prefer areas with a layout that offers opportunities to play, be up high and hide away, compared to a bare space. Within its territory, the kitten will have four distinct areas: the eating area, an area for rest, the toilet and a large area for play.

You should try to not disrupt this organisation, or your kitten could develop behavioural problems. The eating area should not be near the toilet area or your own eating area. 

If possible, avoid the kitchen or dining room so that your kitten does not confuse your meals with theirs, which could lead to a nutritional imbalance. 

The position of the rest area changes depending on where the best heat sources are and your kitten will probably choose to rest near a heater or in the sun. If you have a sleeping basket, position it in a warm place near you, as your kitten will enjoy being close to you. 

Choose an area away from the kitten’s food for the toilet area. The litter box should be easily accessible. If necessary, have a few positioned around the house. Gradually move the litter closer to the door and then outside if you would like to train your kitten to eliminate outside. 

The play area is the largest of the four and ideally provides ample opportunities for playing, racing about and climbing up high. 

Cats adore places where they can be at the same level as your face and rub against you as they would another cat so your kitten will be prone to jumping on beds, couches, tables or cupboards to be closer to you.

6 to 12 months: Your kitten is an adolescent and will increase the exploration of dominance, including challenging humans. Sexual behaviour begins now if your kitten has not been spayed, if a girl, or neutered, if a boy.

Kittens orphaned or separated from their mother and/or littermates too early often fail to develop appropriate ”social skills” such as learning how to send and receive signals, what an ”inhibited bite” (acceptable mouthing pressure) means, how far to go in play-wrestling and so forth. 

Play is important for kittens because it increases their physical coordination, social skills and learning limits. By interacting with their mother and littermates, kittens explore the ranking process ”who’s in charge” and also learn ”how to be a cat”.

While these stages are important and fairly consistent, a cat’s mind remains receptive to new experiences and lessons well beyond kittenhood. Most cats are still kittens, in mind and body, through the first two years of life.

Remember to take your kitten for vaccinations at 6 – 8 weeks of age with a booster vaccination after a month. A 3-in-1 vaccine is given, which treats for the 3 most common and contagious diseases in one vaccine. 

At 3 months old, your kitten will receive their first Rabies vaccine with a booster required a month later. Deworming can be done from the time they are 2 weeks old and repeated bi-weekly (2-week intervals) until they are 6 weeks old. 

The vet will give a dewormer at every vaccination. This is a good time to get your little one used to go to the vet. Try to make it a positive experience as well using treats and play. Good associations at the vet could save stressful experiences for everyone later on. 

It is important to make it a lifelong relationship and the most pleasurable experience for all Involved. Do not hesitate to call your veterinarian for advice or questions on your new kitten.

My cat has suddenly gone lame in her hindquarters and seems to be in a lot of pain

What is Feline Aortic Thromboembolism?

Feline Aortic Thromboembolism (ATE) is a condition in cats where a big blood clot settles and blocks the main artery (the aorta) running from the heart to the cat’s hind legs.  The clot typically settles near the pelvis, where the aorta divides into the two main arteries that extend into the legs.

It is almost like the clot itself has two legs extending down into the two main arteries. This type of clot is known as a “saddle clot” or “saddle thrombus”. This condition is typically associated with heart disease in cats.

ATE most commonly occurs in cats with an enlarged left chamber (atrium). The enlarged heart chamber slows down blood flow and over time the red blood cells start clumping together and form a blood clot.

The blood clot is then pushed out of the heart and down the aorta, where it lodges at the point where the aorta branches into the two main arteries (external iliac arteries) extending into the legs. As a result of the clot obstructing the artery, the blood supply to the hind legs is cut off.

What are the symptoms of a saddle thrombus in cats?

  • Sudden Lameness/ Unsteadiness in the hind legs
  • Decreased Activity
  • Over Vocalisation (Painful ‘Meowing’)

Up to 90% of cats show no signs of heart disease before developing this condition and owners often suspect trauma. If the owner is not present right at the onset of the condition, they may come home from work and find their cat paralysed in the hindquarters and dragging its body forward with the front legs. In such instances, it makes perfect sense that one would suspect that the cat had been run over by a car.

When presented to the vet, the tell-tale signs are usually that the hind leg muscles are swollen and very painful to touch. The legs are also cool to the touch because the warm oxygen-rich blood from the heart cannot be pumped down to the legs.

The nail beds will also either be very pale or very dark. With the blood being blocked higher up, the femoral arteries, which are the main arteries on the inside of the leg taking blood to the paws, will have no pulse. The vet will try and feel this pulse on the inside of the hind legs to establish if any blood is still coming through to the legs.

The cat’s rectal temperature will be abnormally low. Many cats are still able to move their tails and control their bladder and stool functions, however, skin sensation and neurological functions i.e. reflexes are absent. Signs of heart failure (heart murmur, difficulty breathing) may accompany the signs.

How is a saddle thrombus diagnosed?

The condition is mostly diagnosed on the typical clinical signs, but to further confirm the diagnosis the vet may cut one of the toenails down to the quick to see if any blood is coming through to the extremities. With a saddle thrombus, the cut nail will either ooze dark blood or not bleed at all.

The vet may also recommend taking radiographs, performing an ECG or doing an echocardiogram (heart scan) with ultrasound to assess the extent off the condition and potential underlying heart failure.

Occasionally the blood clot may lodge further up the aorta and occlude the blood flow to the kidneys as well, in which case the vet may recommend blood tests to evaluate the kidney function.

How is Feline Aortic Thromboembolism treated?

The condition is often treated through cage rest, pain control and drugs which counter blood clots from forming (often in humans referred to as “blood thinners”) and arterial dilators.

Due to the severe pain that this condition causes, Opioids (morphine/fentanyl class) are usually the drugs of choice for controlling the pain. Additionally, the vet may decide to lightly sedate the cat if it is very distressed.

Blood-thinning drugs may theoretically prevent further blood clot formation, while ACP or hydralazine might dilate the blood vessels to aid blood flow to the affected areas. There is however no evidence that these drugs have any benefit over cage rest alone.

Surgical removal of the blood clot carries very high risks and is generally not performed. The concurrent heart failure will also need to be managed. The cat may be kept on a drip for a while and the vet will prescribe medications for it to take for the rest of its life.

If the cat survives past the first few days, it will start regaining its limb function after 10-14 days and will be fully recovered after 4-6 weeks. Some residual deficits may be permanent.

Several drugs such as aspirin, heparin, warfarin have been suggested to prevent blood clots forming in cats diagnosed with heart disease, however, there is no evidence of these drugs being effective and the side effects can be quite severe; thus your vet might opt not to use them at all.

It is important to NEVER use human medication for the treatment of cats unless the vet has prescribed it. Some human medicines like Panado is fatal to cats and one should never treat your cat with a human medication unless it was prescribed by a vet.

If the condition is left unattended, the cat may become permanently paralysed and the skin and muscles may start dying off. This may result in wounds needing surgical treatment or even amputation of a leg. In severe cases, additional blood clots may lodge at various points throughout the rest of the body, ultimately leading to death.

What is the prognosis of a saddle thrombus in cats?

The prognosis is generally guarded, with only 33-50% of affected cats surviving and recovering well enough to be discharged from the hospital. Unfortunately, recurrence of the condition is very common.

Due to the guarded prognosis, the high risk of recurrence, and the presence of heart failure, the decision to euthanise your cat (put to sleep) is often the most humane option.

My dog has what looks like a red cherry stuck in the corner of its eye

Introduction to cherry eye

Prolapsed gland of the third eyelid

A cherry eye is a non-life-threatening condition that occurs in dogs, and less often in some cat breeds.  It is an extremely descriptive term, as one can see an oval, bright red swelling in the inside corner of an affected dog’s or cat’s eye, resembling a cherry. As a pet owner one can easily become quite alarmed by seeing this, but fortunately, it only causes slight irritation to the dog initially and you will have time to attend to it and take your animal to the vet before the condition gets out of hand. It is never a good idea to just leave it be. The condition tends to occur more commonly in younger dogs and cats, usually between the ages of 2 and 6 years.

How does it happen that an animal develops a cherry eye?

A cherry eye is in actual fact a protrusion (or bulging out) of the gland of what is colloquially called the third eyelid. Dogs and cats have three eyelids, the top and bottom lids that close up and down over the eyeball as in humans, and then a third eyelid, otherwise called the nictitating membrane underneath the upper and lower eyelids. If you press on the eyeball through the upper eyelid, you will notice the third eyelid moving across the ball of the eye from the inside corner of the eye towards the outside corner of the eye.  This eyelid contains a gland that produces up to 30% of the tear production of the eye. The third eyelid provides extra protection to the animal’s eye and keeps the eye moist. The gland in the nictitating membrane is anchored to the corner of the eye by a connective tissue band. For reasons unknown, this connective tissue starts to weaken and the gland slips out of its pocket. If this happens, the gland is exposed to sun, wind, dust, and trauma from the outside. The gland becomes red and swollen, and eventually painful, due to inflammation. One or both eyes may be affected at the same time. The most common breeds affected by this condition are Beagles, Bulldogs, Spaniels, Shih Tzus, Pekingese, and other brachiocephalic (flat-faced) breeds. The condition is rare in cats but Burmese and Persians seem to have a higher incidence of cherry eye.

Other clinical signs associated with cherry eye.

You will quickly notice the red swelling in the corner of your animal’s eye. Other signs that you might notice are a mucoid discharge from the eye and/or redness in the tissue surrounding the eye, called conjunctivitis. Your pet might also show you he/she is experiencing discomfort by pawing at the eye or rubbing his/her face against objects. This can cause even more trauma to the exposed gland.

Course of action with cherry eye

Due to the fact that some dogs don’t seem phased by the popped out gland, some owners might opt to leave it like that. Not treating the gland may however cause more serious problems to the affected eye in years to come. As more damage is inflicted onto the popped out gland, the amount and quality of tear film that protects the eye will decrease causing chronic inflammation and irritation to the eye. The best would be to get treatment of the infected cornea eye as soon as possible. The vet will examine the eye closely and will usually recommend replacing the gland surgically. The vet may stain the cornea with a fluorescein stain to check for ulcers on the eye itself that might have occurred during protrusion of the gland. A few decades ago, it was common practice to remove the gland surgically when it protruded. This is not the practice any longer because by removing a gland that produces tears, the affected eye can dry out causing a condition called keratoconjunctivitis sicca, or more commonly referred to as ‘dry eye’. It is therefore no longer recommended to remove the gland surgically, unless the gland is so traumatised that it will lose its function in any case. Replacing the gland into its original position is usually done under general anaesthesia by anchoring the gland in its pocket with suture material. For an experienced veterinary surgeon it is a relatively easy surgical procedure to perform. The most common complication is a re-occurrence of the cherry eye and trauma to the cornea by suture. If the condition re-occurs it certainly does not mean that the vet did a hopeless job. Between 5 and 20% of dogs have a recurrence of the condition after the surgery. The reason is that the gland can protrude and prolapse to the other side where the sutures were not placed. If it happens the procedure just has to be repeated. There is no way of predicting whether your pet will be one of the unlucky ones where the condition recurs after the initial surgery.

Conclusion

It is not clear why the connective tissue of the third eyelid housing the tear gland weakens causing a cherry eye other than that there seems to be hereditary component.  It is therefore not recommended to breed with affected dogs. Taking your dog to be examined by the vet as soon as you see the signs of cherry eye, can save you a whole lot of problems with your pet’s eyes later in his/her life, and even save his or her eyesight.

My dog’s nose seems to be all clogged up and hard and he is not well at all

Canine distemper

Following recent outbreaks of Distemper (Hondesiekte in Afrikaans) in Kwa Zulu Natal and Gauteng, it is important to have an understanding of this disease which is fatal in half of all cases of dogs that contract the disease.

What causes Distemper?

Distemper is a virus disease caused by the Canine Distemper Virus or CDV. This virus is a morbillivirus in the Paramyxoviridae family which is a virus group that affects humans, vertebrates and birds. This specific virus is not transmissible to humans but specifically targets dogs hence the name “Canine” Distemper Virus. The virus is closely related to measles virus in humans, and also to rinderpest virus in cattle, which at the beginning of the previous century almost killed the entire cattle population of Southern Africa. It’s a nasty virus.

What are the symptoms of Distemper?

The virus attacks mainly the respiratory system (from the nose right into the lungs), the gastro-intestinal system (from the mouth, through the stomach into the small and large intestines) and the central nervous system (mainly the brain). This means that the symptoms associated with the disease will be related to problems with these three main systems. In acute to subacute infections the dog will usually develop a fever within a day or two from being infected. The dog will go off its food and become weak and lethargic

Respiratory system symptoms may include a clogged up nose typically with mucous or slime that becomes hard, and hardening of the nose itself. This is a very telling symptom of Distemper but is by no means the only, or most typical, presentation of the disease. A dog with distemper may have a perfectly normal nose and still have the disease. Many times there will also be a discharge in the corners of the eyes. Other respiratory symptoms include coughing, sneezing and difficult breathing if the virus attacks the lungs.

If the gastrointestinal systems is affected you may see vomiting and/or diarrhoea.

If the central nervous system is involved you may have muscle tremors, a dog which seems disorientated and walks around as if they are drunk (ataxia), hind limbs which are dragged or seem lazy (paresis), a dog which cannot get up or falls down when they do get up (paralysis), and even seizures. Other symptoms which are not immediately visible and which only the vet may be able to pick up are lesions on the retina at the back of the eye, or an inflammation in the front of the eye called anterior uveitis. Hardening of the footpads  (hyperkeratosis) was previously quite common because of the strains of virus involved, but seem to be less common these days.

How is Distemper diagnosed?

There are several blood tests which can be done by the vet, but it is a difficult disease to diagnose because unlike a disease like biliary or tick fever in dogs where you can see the parasite in the blood with a bloodsmear, in Distemper, as with all other virus diseases, you cannot see the virus as it is simply too small. The trouble with the blood tests are that they are often not conclusive. The reason for this is that some of the tests, test if the dog is building up antibodies (“soldier”) against the virus. However a dog that may previously have been vaccinated may show antibodies and not have the disease. Sometimes the dog may die acutely before the body was able to produce neutralising antibodies, so in that case the test may be negative, yet the dog still had the disease.

Another type of blood test where the white and red blood cells are counted and where the white cells are less than usual, called lymphopenia,  may give an indication that the dog has a virus disease but it will not tell which virus the dog has.

If the dog has central nervous system symptoms, the fluid around the brain and spine called Cerebro Spinal Fluid (CSF) may contain antibodies but once again it may not be 100% diagnostic. There are other tests which can be run on the CSF (cell or protein content) which may be indicative, but does not conclusively confirm that the dog has Distemper.

There are a number of other diseases which can present with similar symptoms which the vet will have to rule out. On the respiratory side there is Kennel Cough or other upper respiratory tract infections. On the intestinal side there is Parvovirus and Coronavirus, parasitism like worms or Giardia, bacterial infections, toxin ingestion or inflammatory bowel disease. On the neurological side there is granulomatous meningoencephalitis, protozoal encephalitis (toxoplasmosis, neosporosis, babesia), cryptococcus or other infections (meningitis, Ehrlichiosis), pug dog encephalitis and lead or other poisoning.

Clearly Distemper is not a simple disease to diagnose and the vet will often have to rely on the age of the dog, its history, the results of the clinical tests and the appearance of the clinical symptoms, to make a diagnosis of Distemper.

How is Distemper transferred?

The virus is typically inhaled through the air from other sick dogs and also from physical contact with infected animals. The virus can survive for a period of time in the environment and if a dog which carries the virus sniffed around or spent time in a certain environment, it will leave tiny, tiny droplets (aerosol) which contain the virus in that area, which can then infect other dogs. A dog which is infected will inhale or ingest the virus and the virus will quickly spread through the mucous membranes to the local lymphnodes (these are like the remote “army bases” of the body which has to protect the body against invasions) where it will multiply and within one week the whole body will be infected.

How is Distemper treated?

Vets have over the years tried antiviral drugs of which there are very few anyway,  and none have been effective. As with almost all virus diseases one has to support the body in its own fight against the virus because it is only once the body has been successful to produce antibodies (the “soldier cells” which kill the “terrorist” or virus), that the dog will be able to overcome the disease. Often, when the body is attacked by viruses and the immune system is fighting hard to overcome the infection, bacteria will cause a secondary infection and make the whole situation worse. Therefore antibiotics are often administered even though it will do nothing against the virus, but at least it will help the body fight off opportunistic bacterial infections and help the body to overcome the disease. Other treatment depends largely on which systems are affected and to what extent. The vet will typically give symptomatic treatment, for example if the dog has seizures, the vet may administer a drug to help contain the seizures and make them less violent. Certain drugs should not be given and it is important to consult with the vet in case you think your dog may suffer from Distemper.

Can Distemper spread to humans or cats?

In the past it was suspected that the Canine Distemper Virus can cause Multiple Sclerosis in humans. However this has been proven NOT to be the case and as far as we know the disease cannot spread from dogs to humans. Similarly, as far as we know, this disease cannot be transferred to domestic cats.

What is the prognosis should my dog contract Distemper?

Unfortunately the prognosis is not good and the mortality rate is 50%. It will be very difficult for the vet to tell whether your dog will fall in the 50% that will survive or the 50% that will not make it. The vet will have to assess the extent and severity of the clinical symptoms and the progression of the disease and based on that, will advise you whether treatment has any chance of success or not. An important thing to remember is that even though the disease may not appear to be very far advanced when you first present your dog to the vet, and there seems to be early good response to treatment, like the clogging of the nose and the discharge in the eyes clearing up, the dog may still develop fatal central nervous system signs later on. It is important to understand that the vet has no control over which way the disease may go and will do his or her best with your animal’s best interest at heart, when recommending treatment or not.

Can Distemper be prevented?

A resounding yes! Vaccination has been hugely effective in almost eradicating this disease and all dogs should be vaccinated, preferably yearly at the same time as their annual health exam. Your vet will give you more specific advice related to the area you live in and the risk factors involved and should the vet think that annual vaccination is not necessary, the vet will advise you accordingly.

Puppies and old dogs are more commonly affected and all puppies should go through an initial vaccination program from 6 weeks onwards to provide protection. Puppies born from mothers who were vaccinated and had antibodies will get this protection from the initial milk or colostrum from the mother in the first few days after birth. The protection provided through the mother’s milk will start waning after six weeks and this is why vets normally start vaccinating at this time, and repeating the vaccination three or four times with booster vaccinations with monthly intervals and then yearly thereafter.

What do I do if I suspect my dog to have Distemper?

Get them to the vet as soon as you can. Home remedies or treatment is unlikely to give your dog a fighting chance. Proper supportive and secondary infection treatment remains the mainstay of treatment.

Most importantly, have your dog vaccinated. Prevention is always better than cure!

My pet injured its eye!

Just like in people, the eye of a dog or cat is a delicate structure that can be affected by a huge number of different conditions. This article will cover trauma to the eyelids, third eyelid and cornea.

Anatomy of dogs and cats eyes

The eye of the dog and cat is very similar in structure to the human eye but there are one or two differences. Both a cat and dog’s eye is globoid (round) in shape. The part of the eye exposed to the outside is protected by the eyelids and eyelashes, just as in people. The cornea is the see-through part of the eye. It is a thin layer, allowing light to pass through the pupil and lens to the back of the eye.  The white of the eye is known as the sclera. The conjunctiva is the pink part of the eye that can be seen between the eyelids and the eyeball. Dogs and cats both have an extra membrane, known as the third eyelid or nictitating membrane.  This membrane can be seen in the inner angle of the eye and sometimes it can cover most of the eye, particularly following trauma. 

http://corinnaklupiec.weebly.com/blog/archives/05-2014

Trauma to the eyelids

The eyelids are the first structures protecting the delicate eyeball from the outside and potentially trauma. Due to being more active, getting into fights and exploring, cats and dogs are more prone to traumatizing their eyelids. Lacerations or cuts to the eyelids are a fairly common injury seen in most veterinary practices.  If there is any trauma to the eye, it is important to take your pet to the vet. Some injuries may be superficial and cleaning the wound with disinfectant may be all that is required. In other cases, the eyelid may need to be stitched back together. The sooner the eyelid is stitched, the better the chances of it staying together. It is very important that the eyelid margin (that is the part that the eyelashes attach to) remains smooth. If there is a kink in the eyelid margin, this can lead to further trauma to the eye and it can damage to the sensitive cornea.  Once the eyelid has been stitched, your pet may require eye drops for a few days to assist with the healing and prevent any infection.

Trauma to the third eyelid

Sometimes the third eyelid can be lacerated. This is commonly seen in cats that have been involved in a fight and have been scratched in the eye.  If the third eyelid is badly traumatized, it may need to be sutured.

Trauma to the cornea

Corneal ulcers

The most common injury seen to the cornea is corneal ulceration. This is where the first outer layer of the cornea (the epithelium) is damaged, exposing the more sensitive inner stroma of the cornea. This can be very painful. A scratch to the eye or a splash of shampoo or other caustic substances can cause an ulcer.  There are some viruses, such as herpes virus in cats that can also cause ulcers in the cornea. Often we do not know what has caused the ulcer. If you notice your dog or cat squinting, or the eye is closed and seems painful, then it is important to take them to the vet immediately. Often the conjunctiva will also be inflamed. This is known as conjunctivitis. The eye may also have some discharge.

The vet will examine the eye with an ophthalmoscope. This will allow the inside of the eye to be seen and ensure that there is nothing else going on. The vet will then perform a fluorescein test. This is where an orange stain is placed on the cornea. The eye is then looked at with a UV light (blue coloured light). If there is any defect in the cornea, this will show up as bright green. The corneal epithelium does not take up any stain but if the stroma is exposed it will take up the stain. 

Corneal ulcers can vary in size and severity. It is important to start treatment as soon as possible as the quicker it is treated, the more likely it is to heal. If the injury is superficial and small topical treatment with eye drops remains the most effective treatment. It is important that eye drops containing corticosteroids are not used as this delays the healing of the cornea and can, in fact, make the ulcer worse. Other drops and medications may be needed for pain control or to maintain the eye’s lubrication. The eye will need to be assessed daily to ensure that it is healing. In some cases, further treatment will be needed. In severe cases, the ulcer may need to be covered with either the third eyelid or some conjunctiva. This procedure will need to be done under general anaesthetic. The flap is placed over the cornea and sutured in place to give the cornea time to heal. The vet may even give you a referral to a specialist veterinary ophthalmologist which is a vet who would have done between four and six years of extra study over and above their veterinary degree, to become an eye specialist.

There is no set time to how long the cornea will take to heal but daily checkups are required initially to ensure that the condition is not deteriorating. In very severe or long-standing cases, the eye may even need to be removed. 

Foreign bodies within the eye

Penetration of the cornea by foreign bodies such as thorns, glass and sand can be seen in dogs and cats. This is normally very painful and can quickly lead to infection within the eye. If the foreign body is just penetrating the surface of the cornea, it may be removed with the aid of local anaesthetic. In severe cases, where the foreign body has penetrated deeper into the cornea and eye, it will need to be surgically removed. Fine instruments are often required in order not to damage the eye further and this procedure may need to be performed by a specialist ophthalmologist. If your pet is showing any signs of pain or discharge to their eye, it is important to seek immediate veterinary attention.

What is the prognosis with eyelid and corneal trauma?

The prognosis of injuries to the eyelids and cornea will depend on the severity of the trauma. If treated quickly, then permanent damage to the eye is minimized but this does depend on how extensive the injury is. The cornea scars white and so if the ulcer is very deep or long-standing this can affect the eyesight, particularly if the scar forms over the part of the cornea that is in front of the pupil. It is important to remember that the quicker it is treated, the more successful the treatment is likely to be. If you notice any pain, discharge or redness to your pet’s eye, it is important to take them to vet for an assessment. You may ask how do you determine that your pet experiences pain in their eyes? Apart from you visibly seeing damage to the eye or noticing an eye which is excessively teary, you will most likely notice your pet scratching at the injures eye with their front paw or alternative scratching the eye or face on furniture or the carpet, in an effort to relieve the discomfort and pain. If you are in doubt, err on the conservative side and get your pet to the vet as soon as you can. The loss of eyesight through the loss of an eye is simply not worth risking seeing whether the animal will get better by themselves.
