Heartworm Disease
Heartworm disease is a parasitic disease caused by a worm called Dirofilaria immitis. The worm is transmitted through mosquito bites and then grows and lives inside the dog’s heart and pulmonary arteries. The most common signs of heartworm disease include:
- Mild, but persistent cough
- Fatigue after moderate activity
- Reluctance to exercise
- Loss of appetite
- Weight loss
Affected dogs need to be treated with specific antiparasitic drugs and must rest during the treatment period. The condition can be prevented by using anti-heartworm preventive medications. Depending on the geographic region, the preventive medication can be used seasonally or year-round.
