What Is Heartworm Disease?

Heartworm disease can affect dogs, cats, and even ferrets. Heartworms are transmitted by mosquitoes. When a mosquito bites your pet, it injects larvae into the bloodstream. Those larvae migrate to the heart, where they develop into adult heartworms.

Why Heartworm Disease Is Dangerous

Heartworms can be a deadly parasite. Most pets with heartworms do not show symptoms early in the disease, so it can go undetected for many years without the pet owner knowing. As the worms multiply and the worm burden increases, pets begin to develop signs of heart disease.

How Heartworms Affect the Heart and Lungs of Our Pets

Heartworm disease primarily affects the right side of the heart and can lead to right-sided heart failure and fluid buildup in the abdomen.

Common Symptoms of Heartworm Disease in Dogs

  • Coughing
  • Lethargy or fatigue
  • Reluctance to exercise
  • Coughing up blood
  • Abdominal distension due to fluid accumulation

How Heartworm Disease Is Diagnosed

Heartworms are detected with a simple blood test. If the test is positive, chest X-rays are recommended to help determine the severity of the disease and evaluate the heart and lungs.

Heartworm Prevention for Dogs, Cats, and Ferrets

Heartworm disease is easily prevented with year-round heartworm prevention that is available for dogs, cats, and ferrets.

Heartworm Treatment in Dogs

If a dog is diagnosed with heartworms, treatment is available. However, there are significant risks and potential side effects if proper precautions are not taken. For this reason, prevention is the most important step.

Start Prevention Early and Continue for Life

The most important thing pet owners can do is start their dog, cat, or ferret on heartworm prevention at a young age and continue it consistently throughout their life.
