Keep scrolling to learn more.

Heartworm Disease in Dogs

Heartworm disease occurs when an infected mosquito bites a dog or another animal. Once inside a suitable host, the worms reach up to 12 inches in length and reside in the heart, blood vessels, and lungs, resulting in irreversible damage. When left untreated, the parasites grow and multiply continually, which leads to further complications, such as poor health and, in many situations, premature death.

Heartworm disease causes several symptoms, including:

  • Persistent cough
  • Fatigue after even light exercise
  • Weight loss
  • Reduced appetite
  • Bloated abdomen
  • Light-colored gums
  • Labored breathing or shortness of breath

Protecting Your Dog from Heartworm

Heartworm disease is notoriously difficult to treat and causes irreversible organ damage. Preventing the disease is a much better option than attempting to treat it. Heartworm preventatives come in numerous forms, such as injectable medications, chewable pills, and even topicals.

According to the American Heartworm Society, all dogs should remain on heartworm preventatives year-round, even when mosquitos aren't prevalent. All dogs need annual heartworm testing, too, even if they are on a preventative medication. While preventatives are extremely effective, it’s still possible for a dog to become infected with heartworm disease. Having your dog tested every year gives their veterinarian to detect and begin treatment for infections in their early stages when they are most treatable.
