Heartworm Testing

Heartworms are a type of internal parasite that thrive in dogs. Cats are not immune to this parasite; however a heartworm infection is more severe in dogs. A heartworm infection is spread by infected mosquitoes who pass on baby worms when they bite dogs. These worms can live inside the host (dogs) for up to seven years. During this time the worms will mature, reproduce and grow up to 12 inches long reaching important organs such as the heart and lungs. A heartworm infection can result in heart damage and clogged major blood vessels. Due to how severe the infection can become it is necessary to protect your pet from heartworms.

How are heartworms detected?

We use bloodwork to diagnose heartworms in pets. A small blood sample is collected and examined for heartworm proteins. This is known as an antigen test. Heartworm proteins are only detectable in the blood five months after a dog has been bitten by an infected mosquito. The blood can also be examined for microfilariae which can be detected after six months. Additional diagnostics such as X-rays may be performed to see if the worms have affected the heart and lungs.

What are signs of heartworm disease?

Even if you notice signs of infection early, your pet has likely been infected for longer than you realize. Do not hesitate to consult with your veterinarian immediately if you notice these signs:

• Fainting
• Lack of appetite
• Persistent dry cough
• Sickly appearance/low energy
• Sudden weight loss
• Trouble breathing

Please schedule an appointment for your pet immediately at 250-765-2916.

How can heartworms be prevented?

Preventing heartworms is far easier than treating an infection. Treatment is not only expensive but also hard on your pet’s body. Your veterinarian can prescribe monthly preventatives in the form of topical liquids or oral tablets. Your pet should also be vaccinated against heartworms every six to 12 months. Some heartworm preventatives also offer protection from other intestinal worms, feel free to ask your veterinarian for more information.
