Heartworm Prevention

Heartworm Disease and What You Need to Know

North Yonge Veterinary Hospital knows the importance in educating pet owners from Newmarket, York Region, and Toronto on keeping their four legged friends healthy.

We are known as leaders on the education front for health and wellness so your buddy will live a longer and healthier life.

One major area we are experts in is the prevention of heartworm disease in dogs.


A recent study on heartworms in dogs in Canada, one which was published by the Ontario Veterinary College’s Department of Pathobiology at the University of Guelph, reports that this disease is on the rise.

There is no need for panic, heartworm disease is easy to prevent.

Our professionally trained staff at the North Yonge Veterinary Hospital in Newmarket provides regular testing and we offer the best preventive medication to ensure your dog is healthy. We offer a year round preventative program which involves giving your dog a once monthly chewable tablet or applying a topical solution to the skin. Either type of preventative destroys the undeveloped heartworms spread by mosquitoes and eliminates the cycle of the parasites.

heartworm-cats-dogsThe medications we offer not only prevents heartworm disease, but it also treats and controls other types of parasites that includes fleas, roundworms, hookworms and whipworms.

We stress the importance of regular testing simply because your dog could be at risk of heartworm disease in all four seasons – fall, winter, spring and summer.

First up, we highly encourage that your dog undergo a heartworm blood test at our state-of-the-art facility. This is a simple process and doesn’t take long at all. This disease primarily affects dogs, but cats too can also suffer from having heartworm disease. Talk to us and we will ensure your pet gets checked and tested. At North Yonge Veterinary Hospital in Newmarket, we perform the 4DX heartworm test, which also runs a screening test for tick-borne illness such as Lyme disease.

Keep in mind that heartworm disease may result in severe illness or even death, so taking action early will ensure your dog is healthy. Treatment for heartworm disease is available, but it is very costly and does not guarantee your pet will be free from danger.

Many people assume that there are early warning signs of heartworm disease. This is far from the truth. This disease is normally detected once it has progressed and the damages to the internal organs are usually irreversible.

Symptoms of heartworm disease include a chronic cough, general listlessness, laboured breathing, and even weight loss. Your dog may also show signs of tiring easily when walking or running. In some cases they may even collapse due to heart failure.

Talk to our staff today about heartworm disease and take action to ensure your dog lives a long and healthy life. You will be happy you did and so will your four legged buddy.
