Small Animal

There are a few different types of rat poison that all work to kill rodents in different ways. Your pet’s symptoms and treatment will depend on what type of rat poison they ingested.  We at Coventry Animal Hospital recommend using “rat stations” to put the bait into as a safe alternative.

Rodenticides Causing Bleeding disorders

These include Coumarin products such as warfarin and Indanione products such as bromadiolone and brodifacoum. These products inhibit vitamin K being transformed into its active form. Vitamin K is required for certain blood factors that are important for clotting. Signs don’t show until clotting is significantly affected. This can take 3-7 days and effects can last as long as 4 weeks.

Signs that your dog has ingested this poison include lethargy, loss of appetite, painful abdomen, bruising, bloody urine and pale gums. If left untreated, this can lead to death.

If your dog just swallowed the poison, your veterinarian will induce vomiting. Your vet may also want to perform blood testing to evaluate how well your dog’s blood is clotting. This type of rat poisoning is treated with Vitamin K for 2-4 weeks. Dogs with severe signs may need hospitalization and blood transfusions.

Vitamin D Rodenticides:

The toxin in these products is called Cholecalciferol. These products cause a dangerous increase in the calcium levels in the blood. This can lead to severe kidney damage and cardiac arrest.

Signs of toxicity include lethargy, loss of appetite, increased drinking and urination, or sudden death.

Treatment involves being admitted to hospital for fluid therapy and medications to lower blood calcium levels. Frequent blood monitoring is required and your pet may need to be on medications for months depending on the level of kidney damage that was suffered.

Rodenticides Causing Brain Swelling:

The toxin in these products is called Bromethalin. This toxin enters the central nervous system and causes swelling in the brain leading to dangerously high pressures.

Signs can occur hours to days after ingestion depending on the amount ingested. Signs can range from vomiting and depression with small amounts ingested to seizures, muscle tremors and lack of coordination with higher amounts.

Treatment involves hospitalization and supportive care that could be needed for many days. There is also the possibility for permanent neurological damage to occur.

What to Do If Your Pet Swallowed Rat Poison

The first thing you should do is get your pet to your veterinarian. The sooner you get it to your vet, the more likely your vet will be able to induce vomiting and remove the toxin. Further treatment will be based on the type of poison it is and so it is extremely important to bring the rat poison with you! Only with that information will your vet be able to properly treat your pet. It could mean the difference between life and death!

What is crate training?

“Crate training” is teaching your dog to rest calmly in a small kennel or carrier.  Crates can be used routinely for times when the dog is home alone as well as when you are asleep.  It is easiest to train puppies to use a crate, but adults can be taught as well.

Reasons to use crates:

• To prevent destruction to your home from chewing and accidents
• To prevent the dog from hurting itself if it has separation anxiety
• As a safe place, during storms, fireworks or when strangers visit
• When it is getting groomed, boarded, at a vet clinic or traveling
• In the event of an emergency and the pet needs to be evacuated
• During changes in your family situation – including moving, renovations, introductions or losses of pets or people from the home

Eight hours is the limit for crating at one time or less if the dog cannot hold its bladder and bowels for that long.  Assume that a puppy can only hold its bladder and bowels for the number of hours equal to its age in months plus one.  For example, a 2 month old puppy should be given the opportunity to go to the bathroom at least every 3 hours.

How to crate train

Crates can be a wonderful tool for dogs that need comfort, rest or a break from a stressful event.  They are not to be used as a punishment; otherwise, the dog will learn to fear the crate.  All children should be taught to leave a dog alone when it’s in its crate.

What should the crate look like?

The crate should be large enough for the dog to turn around in, but not so large that a puppy can have an accident at one end and walk away from it at the other.  The crate size may need to be altered as the puppy is growing.  Sturdy plastic carriers are a good choice for dogs under 30 pounds, but a metal crate may be necessary for a larger breed dog.  It is normal for a puppy to chew what is in the crate, so putting bedding into the crate may not be a good choice for your dog.  Instead, you can offer your dog several chew toys, as long as it is supervised.  Bedding in the crate may also absorb accidents and make house training more difficult.

Where should I put the crate?

Place the crate in a quiet part of the home where the puppy will have few distractions and feel comfortable resting.  Putting the crate in your bedroom or living room is a good choice so that the puppy is not alone.

Where do I start?

Start by feeding your dog’s meals in front of the crate opening.  Once it is are comfortable with this, you can place the food just inside the crate.   Eventually, you can move the food to the back of the crate.  After the meal, offer some treats by reaching inside the crate or throwing treats to the back to encourage the dog to remain inside.  Slowly increase the length of time between treats and have the dog wait patiently inside the crate until the next treat is offered.  When your dog has become accustomed to the crate, you can close the door for brief periods.  If the puppy is vocal in the crate, ignore it to avoid reinforcing undesirable behaviour.  Continue to offer treats intermittently when it remains quiet.  Gradually increase the length of time you leave the room.  You do not want to trick the puppy and close the door when it is sleeping, otherwise it will distrust the crate.

Keep your puppy on a feeding and bathroom break schedule, so that if it learns that it will not be left in the crate with the urge to go to the bathroom.  Schedule a bathroom break at the same time every night if one is needed in order to avoid accidents.

Any time a family member wakes up during the night, it will also wake the puppy.  When puppies wake, they should be given a brief opportunity to go to the bathroom outside.  Don’t play with them during the trip and put them back to bed calmly.  Let them out first thing in the morning and again after their breakfast.  During the hours that you are with your puppy, give it ample opportunities for proper bathroom habits and gradually decrease their frequency.

Want more info on crate training? 

Please ask our technicians at Coventry Animal Hospital for more tips for your specific dog’s needs.  Crate training isn’t an approach that works well for all dogs.  It is a safe space for a dog but remember that they also need lots of exercise, mental stimulation and time with its family in order to thrive.

Here at Coventry Animal Hospital, we have seen our fair share of cases of GDV. GDV (also known as torsion or bloat) is an emergency condition that occurs most commonly in large, deep chested dogs but can occur in dogs of any size. GDV occurs when the stomach fills with gas and then twists on itself. This is an emergency and life threatening condition since blood circulation is cut off by the twist and expansion of the stomach, which can lead to shock.

What are signs of GDV?

Dry retching/attempting to vomit without producing anything
Drooling
Pacing/restlessness
Bloated looking belly

How is GDV diagnosed?

If you suspect your dog may have GDV, take your dog to a veterinarian immediately! Your vet will perform a physical exam that may lead to highly suspicious signs of GDV. If your pet is stable enough, the vet will perform an X-ray to diagnose the torsion. If not, your vet will stabilize your dog by removing some of the gas from the stomach first.

How is GDV treated?

GDV is treated by emergency surgery to correct the position of the stomach. During the surgery, your vet will evaluate the condition of the stomach and spleen. The spleen is close to the stomach and may twist with it and be damaged. If the spleen looks damaged, it will be removed. The stomach will also be assessed. Any dead tissue of the stomach will have to be removed as well. The stomach will then be anchored to the body wall in a surgery called a “pexy” to prevent it from twisting again.

Your pet will also receive emergency fluid therapy and other medications to help with shock. After surgery, your dog will require extensive monitoring as it can be prone to dangerous heart arrhythmias the day following.

Unfortunately, prognosis is variable for dogs that get GDV. The only way to increase your dog’s chance of survival is by getting your dog to the veterinarian as soon as possible when you notice something is wrong.

How do I prevent GDV?

Stress is the only factor that has been consistently shown to play a role in dogs that get GDV, however that is not always the case. No other factors have been directly linked to it. In deep chested dogs that have a higher risk of bloat, a surgery called a “gastropexy” can be performed. This surgery involves anchoring the stomach to the body wall to prevent it from twisting. This can be done at the time the dog is spayed or neutered. Breeds prone to developing GDV include Great Danes, German Shepherds, and Standard Poodles.

What is dental disease?

Bad breath is a big red flag indicating something is wrong in your pet’s mouth and should not be ignored.  Broken teeth, red gums, excessive drooling or discharge/bleeding from the eye, nose or mouth are also abnormal.  These can be symptoms of dental disease.  Other signs may include facial swelling, pawing at the mouth, chattering jaw, chewing food on one side or reluctance to open or close the mouth.  Although our pets may not tell us they are painful, dental disease hurts.

Dental disease is caused by bacteria below the gum line.  It is a condition that will continue to worsen if left untreated.  Dental disease can have negative effects on pets’ organs including the heart, lungs, liver, kidneys and joint; as bacteria from the mouth enters the bloodstream.

The good news is that this disease is reversible.  When there is pain in the mouth, it is not the time to start trying to brush your pet’s teeth – it is time for a professional dental cleaning.  During a physical exam, a veterinarian can diagnose dental disease, but anesthesia and dental x-rays are required to see the full picture below the gum line.

Dental cleaning when a cat or dog is awake does your pet a disservice, as only a fraction of tartar can be removed and is a cosmetic procedure only.  As the pet is wiggling around, there is a greater chance of causing it harm.  The teeth may look whiter, but the painful gum disease is still festering and can lead to tooth loss.

What is dental prophylaxis?

During a dental cleaning at a full service clinic such as Coventry Animal Hospital, your pet is anesthetized to prevent it from wiggling around, control its pain and protect its lungs respiratory system from inhaling bacteria.  A registered veterinary technician or veterinarian will probe the gum pocket to check for deep pockets that indicate disease around the tooth.  If the pockets are small, scaling the teeth clean may be adequate therapy; but in more advanced cases surgical extraction is warranted.  Root canals and complicated orthodontic cases are performed by a veterinary dental specialist on a referral basis.  Teeth are polished and fluoride is applied.  When the pet wakes up, it may have to eat softened food for several days, as the gums are tender.  If teeth were extracted, the pet is sent home with pain medication.  Home dental care and strategies to prevent dental disease are discussed during a post-operative visit.

It’s never too late to make the decision to control dental disease in your pets.  Coventry Animal Hospital encourages you to ask us about dental cleanings for your cat or dog in order to maximize a healthy, pain-free life for your pet.

There are many human medications that can be very dangerous for your pet, even in small doses. While these drugs are safe for humans, dogs and cats often metabolize them differently, resulting in very different effects. Coventry Animal Hospital will describe some of the most common medications that we see given to pets that can have serious consequences:

Tylenol (Acetaminophen): While Tylenol is considered a safe drug for humans to take, it can be fatal for your pets, especially cats. One pill is enough to be fatal as cats do not possess the liver enzymes necessary to metabolize it properly.  It will damage a cat’s red blood cells, limiting its body’s ability to carry oxygen to important tissues. Tylenol can cause severe stomach upset, ulcers and liver failure in dogs.

Other NSAIDS (Aspirin, Ibuprofen, etc): Any NSAID medication not prescribed by your veterinarian has the potential to seriously harm your pet. It can cause serious stomach upset – including severe ulcers. IT can also cause damage to your pet’s kidneys, eventually resulting in kidney failure.

Pseudoephedrine (cough medications, allergy medications, etc.): Any medication listed as “non-drowsy” may include this ingredient. This medication can be dangerous, even at low doses (just one tablet can be lethal in a small dog or cat!). Ingestion can result in vomiting, seizures, and death.

Sleep Aids (Xanax, etc.): While these medications are occasionally used in pets (depending on the amount), medications used for sleep aids in humans can actually have the opposite effect in dogs such as agitation, aggression, and hyper-excitability. This is often followed by severe lethargy. Sleep aids can result in lethal liver failure in cats.

Anti-depressants (Cymbalta, Prozac, etc): Similar to sleep aids, these medications are sometimes used in pets; but depending on the dose, can result in aggression, agitation, decreased appetite, and seizures. A cat having just one pill can result in a highly toxic dose.

Estrogen/Steroid Creams: Pets can easily be exposed to these creams by licking owners after the owner has applied them. While single time exposure may not be significant, regular exposure can cause bone marrow suppression and even result in an endocrine disease called Cushing’s disease. This disease causes weight gain, hair loss, and increases in drinking and urination.

All human medications have the potential to do serious harm to your pet and some can have lethal consequences. Never give your pet a human medication without first contacting your veterinarian. If your pet swallowed medications it shouldn’t have, get it to a veterinary clinic right away. The sooner you get it there, the more likely your vet with be able to induce vomiting and limit the dangerous effects medications can have. Make sure to let your veterinarian know exactly what medication your pet ingested, as it is critical information for your veterinarian to have to make an appropriate treatment plan to save your pet’s life.

The technical name for blocked cats is Feline Urethral Obstruction.

What is Feline Urethral Obstruction? 

Feline urethral obstruction occurs when the urethra (the tube that drains urine out of the bladder) becomes blocked. While this sometimes occurs because of urinary stones obstructing the urethra (urolithiasis), it more often occurs in cats because of “urethral plugs” made up of mucus, protein, and cells. These obstructions make it very difficult for the cat to pass urine.

When your cat is unable to pass urine, the kidneys are no longer able to remove toxins out of the body and maintain a balance of your cat’s electrolytes. This can lead to kidney damage, fatal heart arrhythmias and death. It can take as little as 24 hours for a cat to die because of this condition. This condition is also extremely painful.

Is my cat at risk?

The exact cause of this condition is unknown; and so we don’t know all the risk factors. Males are at greater risk of developing obstructions due to the length and narrowing of their urethra. While it can occur in cats of any age, most affected cats are between 1 to 10 years old. Other risk factors include being overweight, living in multi-cat households, eating an all dry-food diet, having a history of urinary tract infections and having restricted access to the outdoors. One of the most important risk factors is stress. A stressful event (such as a change in something in their environment) is thought to almost always play a role in most cases.

How can I tell if my cat is obstructed?

The first signs to look out for are frequent trips to the litter box while producing very little urine, straining to urinate, blood in the urine and urinating outside of the box. Your cat may also start to cry out in pain as it becomes more distressed.

When should I be worried?

If you notice any of these signs, this is considered a medical emergency and your cat should see a veterinarian immediately! As mentioned above, it is an extremely painful condition that can rapidly turn fatal.

What will my veterinarian do? 

Your veterinarian will pass a catheter (a narrow tube) into your cat’s urethra to relieve the obstruction. Your cat will also be placed on intravenous fluids to correct the electrolyte abnormalities. Pain control, antibiotics and drugs to help relax the urethra will also be started. Your cat will have to remain in hospital for a few days or longer, depending on the severity of the obstruction.

What can I do to prevent this?

While we can’t say how to prevent all cases, there are some things you can do for your cat to reduce the risk of obstruction:

• Add wet food to your cat’s diet.
• Provide clean, fresh water at all times to encourage drinking. This is very important! Many cats do not like food floating in their water, so try to keep the water bowl away from their food dish. Consider using a water fountain, as some cats enjoy flowing water.
• Make sure to keep your cat a healthy weight. If your cat is overweight, talk to your veterinarian about a weight loss program.
• Provide enough litter boxes (one for each cat in the household, plus an additional one). Keep them clean and in a quiet area. Try different sizes and litters to see what your cat prefers.
• Decrease stress. Try not to change your cat’s routine, consistency is key! Consider using pheromone sprays or diffusers when anticipating a stressful event. Encourage playtime and have many safe hiding places for your cat to use.
• If your cat had urinary stones, use a specially formulated veterinary diet to help prevent them from reoccurring.

Please do not hesitate to contact us at Coventry Animal Hospital immediately, if you suspect your male cat is unable to urinate.

Both public health and Coventry Animal Hospital staff take possible rabies exposures seriously and with good reason.  Rabies is a virus that is almost always untreatable and fatal once symptoms begin.  Positive wildlife cases have been confirmed in our area.

What is Rabies?

Rabies is a virus that requires direct transmission from an infected animal’s saliva to an open wound, such as a scratch or bite.  The virus will slowly penetrate to the local nerves and travel to the brain.  Once at the brain, it will cause neurologic symptoms in several stages.  The initial stage includes a personality change and licking the site of the original bite.  Later stages involve the animal becoming overly reactive to sounds and light, hallucinating and becoming aggressive and biting anyone in sight.   The last stage involves frothing at the mouth due to an inability to swallow and they become progressively paralyzed, from starting in the back end and spreading up to the muscles that control breathing, eventually leading to death.  Once clinical signs start, there is no treatment and it is nearly always fatal.  Unfortunately, rabies can be difficult to diagnose, as not all individuals will have these symptoms and other diseases that affect the nervous system can mimic rabies.

Wildlife such as bats, skunks, raccoons, foxes and coyotes commonly carry this virus and are at risk for spreading it.  We recommend against handling these species, as exposure to their saliva may transmit the virus.  Any mammal (human, cat, dog, or livestock) that is bitten by these species may be at risk for rabies.

If you are bitten by any animal (wildlife or domestic), we advise you to contact your health care provider or the local District Health Unit (in our case, Perth or Huron County).  You also need to contact the Health Unit if you are bitten by your own cat or dog, as it may need to undergo quarantine.

If your pet is bitten by wildlife, please contact our clinic.   It is important to keep the vaccine status of all of your pets up to date due to public health risk.  Even dogs and cats that are exclusively indoors should be vaccinated routinely.

Does your dog ever drink water from sources outside? Does your dog ever have bouts of diarrhea? If so, your dog may have Giardia!

What is giardia?

Giardia is a protozoal parasite that lives in the intestines of infected animals and humans. While feeding in the intestines, Giardia parasites eventually form cysts around themselves and are passed through feces into the environment. The cysts are able to live for months in many different environmental conditions, and so Giardia is very common.

Where do dogs get it?

Dogs are infected with Giardia when they ingest Giardia cysts. The cysts break down in their digestive tract and the cysts attach to their intestinal wall. The most common source of Giardia is from contaminated water. However, Giardia is very common in the environment (can be anywhere an animal has pooped).

What are the signs?

Most dogs show no signs of infection. Healthy adult dogs, immune system typically can handle the infection. However, in some cases, especially puppies, giardia can cause diarrhea.

How is it treated?

If your dog has diarrhea, it is best to take it to the veterinarian for a thorough physical exam. Here at Coventry Animal Hospital we recommend that you also bring a fecal sample with you (as fresh as possible!). Your veterinarian will be able to use this sample to check for Giardia. Once diagnosed, Giardia is easily treated with specific medications. You should also bathe your dog once you start treatment.

How can I prevent Giardia?

Since contaminated water is the most common source, preventing your dog from drinking water from outside is the best way to help prevent it. That being said, it is difficult to prevent your dog from accessing all sources of the parasite.

Can humans get it?

Humans can be infected with Giardia. Humans also get infected by ingesting the Giardia cysts. This can be done through drinking contaminated water, handling feces and not washing hands, or getting licked by an infected pet that has recently licked their bum! As with animals, most healthy adult humans can fight off the infection themselves with no symptoms. However, immune compromised individuals (children, elderly, pregnant, chemotherapy patients, etc.) could come down with severe diarrhea. To avoid infection, immune compromised individuals should completely avoid handling animal feces. All people should make sure to wash their hands after cleaning up after their pets.

What makes cats different?

Unlike humans and dogs, cats are obligate carnivores. Let’s consider how cats became domesticated. Cats were attracted to human settlements because the rats and mice that humans attracted were delicious and plentiful food sources. Essentially, cats domesticated themselves as they opted to live around humans to access these food sources.  

What does this mean for their nutrition?

What this means to cats’ diets is that they are obligate carnivores who thrive off diets composed mostly of water, then protein and fat, with little carbohydrates (basically the components of a mouse!). Cats get most of their water from their food and are most efficient at deriving energy from protein. In fact in one study, cats actually preferred to eat a higher protein diet that tasted bad versus a higher carbohydrate diet that tasted good.

So what should I feed my cat?

Here at Coventry Animal Hospital, we recommend feeding your cat a mostly canned food diet. Canned food contains more water and protein than a kibble based diet, which is more appropriate for your cat. However, not all canned foods are created equal and some can even be very high in carbohydrates. Ideally the protein source should be meat-based, as cats digest these more readily. You should speak with your veterinarian about the best food to feed your cat. Your cat should receive 2-3 canned food meals per day.

Should I totally avoid kibble?

While cats can thrive on a completely canned food diet, we understand that some cats do like to graze throughout the day. In these cases, feeding some kibble is perfectly fine for your cat. We often recommend a specific veterinary dental diet for cats, as these have been proven to reduce the risk of dental disease.  The focus however, should still be on feeding mostly canned food, with only some kibbles to nibble on through the day. You should speak with your veterinarian about the exact amounts you should be feeding your cat to ensure it does not become an unhealthy weight.

Will my cat gain weight eating more canned food?

No! While you always need to measure food amounts to ensure you are not over feeding your cat, cats that eat canned food tend to maintain a better body condition than those fed kibble. Feeding your cat canned food (being high in protein and low in carbohydrates) can actually help it lose weight. Kibble is far more energy dense than canned food and so it is far easier to over feed with kibble (or for your cat to over eat!).

Will eating more canned food cause bad teeth?

Only veterinary dental specific diets have been shown to help prevent dental disease in cats. Any other kibble does not have this effect. This is why we recommend a dental diet be fed with canned food. That being said, brushing your cat’s teeth is really the best way to prevent dental disease, no matter what it is fed.

How do I know how much to feed my cat?

The best thing you can do is contact your veterinarian. The Coventry Animal Hospital team members can examine your cat and know whether it needs to lose, gain, or maintain its current weight. They can then give you an exact amount of canned food and kibble that would be best to feed your cat. If your cat has any special health needs (diabetes, renal disease, arthritis, urinary crystals, etc), your veterinarian can also give recommendations as to the best diets and supplements that will help your cat with its condition.
