What Is Heartworm Disease?

Heartworm disease is caused by parasitic worms transmitted through mosquito bites. These worms live in the heart, lungs, and blood vessels, leading to severe organ damage, heart failure, and even death if left untreated.

Dogs are the most common hosts, but cats can also be affected—often with less obvious symptoms.

Signs of Heartworm Disease in Pets:

  • Persistent cough
  • Fatigue after moderate activity
  • Weight loss
  • Difficulty breathing
  • Swollen abdomen
  • In cats: vomiting, coughing, or sudden collapse
