Wellness and Vaccination

One of the best things you can do for your pet is to keep him or her healthy. And one of the easiest and least expensive ways to do that is by bringing in your pet for regular exams and vaccinations. Dogs and cats (and other pets) age far faster than people, so significant changes in your pet’s health can happen in a short time.

Small Animal Care

Our veterinarians are experienced in providing specialized care and treatment for exotic companion animals, including ferrets, gerbils, guinea pigs, hamsters and rabbits. We understand their unique health needs and can provide diagnostic, therapeutic, and surgical services, as well as counseling on nutrition, behavior, and general care.

Nutritional Counselling

If your adult dog or cat is healthy, you may have chosen a pet food based simply on whether or not your pet will eat it. Cost may also play a factor in your decision. However, not all pet foods are equal. And feeding the right amount is not as simple as following the directions on the package (they’re just guidelines).

Almost every pet will experience some degree of dental disease in their lifetime! Plaque bacteria thrive in your pet’s mouth (ever smelled that ‘doggy’ or ‘kitty’ breath?). At first they just live on the surfaces of the teeth and gums, but if not removed regularly by brushing or wiping, they will infect the gum tissue, […]

Annual Health Assessments Bringing your pet in for their annual visit is still one of the most important things you can do for his or her preventative healthcare.  You can bring any questions or concerns about your pet for the veterinarian to answer.  The veterinarian will ask you several questions to find out how your […]

Sometimes your pet’s behaviour/actions can tell us they are not feeling well, but other times your pet can hide disease really well. This is why annual examinations and bloodwork is so helpful. Many medical conditions can be found and treated easily with regular veterinary visits and bloodwork. At Avonlea Animal hospital we believe that your […]

MICROCHIPPING Despite your best efforts, accidents can happen and your pet could go missing. Thousands of animals end up in shelters every year. Unfortunately, many of these animals are never reunited with their families because they can’t be identified. A collar tag is a great way to identify your pet; however, if this were to […]

Just like in humans, nutrition is an important cornerstone for the health of your pet. And just like in humans, nutritional requirements change over time, depending on age, lifestyle and medical conditions. For example, cats and dogs with kidney disease require specialized diets, and small breed dogs are often prone to urinary and dental disease […]

Prior to all surgical procedures the patient will have a physical examination and blood work to assess for any problems that need to be addressed prior to surgery or at the time of surgery. During the pre-surgical examination you will be provided with a surgical plan so that you are aware of what procedures will […]

How Ultrasound Works Ultrasonography involves passing a probe over your pet’s skin after the hair has been shaved away, while it emits harmless ultrasound waves (which are like sound waves, but at a higher frequency that we cannot hear). As the sound waves bounce off tissues and structures inside your pet’s body, they are detected […]

When the immune system is exposed to an infectious agent such as a virus or bacteria, it sets to work killing and eliminating it. One of the ways it does this is by making proteins called antibodies that specifically recognize that virus or bacteria and attach to it, flagging it for white blood cells to […]

At some point your veterinarian may recommend that your pet have an x-ray (technically known as a radiograph). This is a diagnostic tool that is very helpful to literally see inside your pet’s body. Examples of things that are commonly diagnosed with radiology include: broken bones, intestinal blockages or foreign objects, heart enlargement, lung conditions. […]

Emily

Amazing clinic! They truly care about their patients and offer the highest level of medical expertise for our dog.

Natasha

The doctors and staff are fantastic! Went for my first visit with Pedro and they were all great. Even when I call for advice. Then today after Pedro had his little man spot taken away and teeth pulled, still amazing before and after the procedures. After all my what I assume must be annoying phone calls checking up on my Pedro they were still so friendly and courteous. Even sent a picture of Pedro recovering! Exceptional skills dealing with Pedro and great communication skills. Not easy to find these days. Very impressed. Love this team!

Michelle

I am so happy with the care I’ve received for all my pets! Everyone is so pleasant from the front desk up to the doctors. They have handled care from puppyhood through spaying and emergencies with compassion and skill. We have also lost two beloved dogs and one Guinea pig to old age- the empathy and compassion helped us in sad times. I highly recommend Drs Rosely and Johnson.

Ann

Thanks to this amazing clinic a wonderful vet and such caring staff. Your compassion and kindness helped us to make the right decision for Bruno Again thank you so much.

Ida

Great clinic and very friendly staff! It took a bunch of calling around to find someone who would look at our ferret but I’m happy we found this one. Dr. Johnson was amazing!

Shaydey

Dr. Rosely and staff are amazing. Professional, friendly and empathetic. I just picked up my puppy and was surprised to find that the bill for her surgery had been discounted. I won’t take my puppies anywhere else.

Dan

Great clinic and very friendly staff. Just wanted to say a big thank you for all your love and support with my kitty Bruno, who sadly I had to say goodbye to on Monday. You can see your love for animals in your work. Thank you.

Shed the winter boots and don the running shoes and hiking gear. It is time to get outside and get active. I for one am so happy to finally be able to see the grass and enjoy those leisurely walks in the woods with Dunkun and Alena.

Exercise throughout the winter has ensured that Dunkun and Alena are fit to run free and enjoy the outdoors without concern of injury due to muscles and ligament weakness that can occur during hibernation. If you have not been active throughout the winter, be sure to take it easy and work up the length and intensity of your exercise. This will help to build strength and reduce trauma to muscles and joints.

For those of you who suffer from environmental allergies, now is the time to start omega fatty acids and antihistamines, which can help to reduce allergy symptoms. If immunotherapy, available in oral and injectible form, is something that you are interested in, you should talk with your veterinarian about performing the required blood tests along with your heartworm and tick disease blood test.

Parasite prevention is a must during the warmer months. With the increase number of ticks moving from the east, west and south, we need to assess the risk factors in contracting tick borne diseases like Lyme disease which can be contracted by humans. Infected ticks can transmit lyme disease, erhlichiosis, and anaplasmosis to dogs. All three parasites cause similar disease complexes including fever, lethargy, blood disorders and joint problems. All three parasites are treated the same and can be treated if detected. However, prevention is key and simple.

Prevention of ticks should be started when the ticks are ready to attack, and this is any time the temperature is above 4 degrees Celsius …so now is the time to treat if your pet is at risk. For those of you who do not like to use medications, you should be checking your dog every time you have been in the long grasses or wooded areas; brush down the fur and even give a bath to naturally removed unattached ticks. It generally takes a tick 12-24 hours to move along the body and find a vascular area to feed upon. Ticks will generally move towards the head, neck, lightly furred regions and between the toes.

Several products are available to help control ticks and thereby help prevent disease induced by tick bourn parasites. However, there is no single product that has a label claim to prevent lyme disease which is transmitted by a specific tick called the deer tick. Bravecto, a chewable tablet is labelled to kill the deer tick within 12 hours of a blood meal, which is before the time it takes the deer tick to transmit lyme disease. Bravecto continues to kill ticks, and adult fleas, for 12 weeks. Bravecto does not treat or prevent heartworm disease. For more information about Bravecto visit www.bravecto.ca/en/.

Let’s not forget about heartworm disease which is transmitted by mosquitoes. In Ontario, heartworm prevention starts in June and ends in November. The timing of heartworm prevention is very important because all heartworm prevention products work backwards to kill the immature stages of the heartworm which are circulating in the dogs blood. Do not forget to give the November dose of your heartworm prevention and do not worry about starting, Revolution or Heartgard to name a couple, when you first see mosquitoes.

Annual or biannual blood work to test for heartworm status is important because the prevention products are not 100% effective and they do not kill adult heartworms. Dogs that contract adult heartworm require specific treatment and veterinary care. The blood test should be performed 6 months after the last date of possible heartworm infection, which is November in Ontario, because it takes 6 months for the immature heartworm to become an adult and produce the antigen that is detected in the heartworm blood test. Be sure to make your veterinarian aware of any warm climate travel outside of Ontario during the winter months because this can affect your dog’s possible heartworm exposure.

Be sure to discuss all of your pet’s health care needs and concerns with your veterinarian. Visit www.dogsandticks.com/ to get more information about parasites and assess your dogs tick risk. Now turn off the computer, get on those sneakers, grab the leash and enjoy the beautiful outdoors.
