Heartworm disease is a potentially deadly infection that starts with the bite of an infected mosquito. From there, the larvae penetrate into a dog’s tissue and migrate to the bloodstream before entering the heart and lungs. Heartworms can live in an infected dog for 5-7 years, so they can produce severe damage in your dog’s heart and lungs over time.

Heartworm disease signs for dogs can include:

  • Coughing
  • Exercise intolerance
  • Difficulty breathing
