Heartworm Testing

A heartworm infection can cause serious health complications for your pet. The disease is more commonly diagnosed in dogs but cats can also become infected. Due to the severity of the disease, we recommend that pets be put on a strict preventative medication schedule and tested regularly. Any late or missed dose of the preventative may leave your pet susceptible to the disease.

How often should my pet get tested?

We recommend having your pet tested for heartworms at least once every year. If your pet lives in an area where they are more exposed to an infection we may recommend more frequent testing.

What are signs that my pet has heartworms?

In most cases, your pet won’t show any symptoms in the early stages of the infection. Once you see any changes in their health you should get veterinary help immediately. If left untreated your pet can suffer from internal damage or even death from heartworm disease. Please call us at 905.707.9059 to book an appointment. Here are some symptoms to be aware of:

1. Swollen belly
2. Loss of appetite
3. Weight loss
4. Continuous coughing
5. Fatigue

How are heartworms treated in pets?

Heartworm disease can be very difficult and expensive to treat. Before your pet gets infected we recommend they begin preventative treatment early. Your furry friend should be vaccinated for heartworms every 6 to 12 months. If they have been diagnosed with heartworms we prescribe medications in the form of topical creams or oral medications.

After your appointment, a staff member will return your pet to you outside, and take care of any needed medications and payment.
  • Continue the use of credit cards as the preferred payment method.
  • Continue with curbside pickup of food and medication (unless you have used our online store and are having your order delivered directly to your home).
