Heartworm disease is one of the most dangerous parasitic infections your pet can face. Transmitted through mosquito bites, heartworms can grow and thrive in the heart, lungs, and blood vessels, leading to severe health complications. March is a great time to learn about heartworm prevention, as mosquito activity increases with warmer weather.

What Is Heartworm Disease?

Heartworm disease is caused by Dirofilaria immitis, a parasitic worm spread by mosquito bites. Once in your pet’s bloodstream, heartworms grow into adults, causing damage to the heart and lungs.

Symptoms of Heartworm Disease

In dogs, common signs include:

  • Persistent coughing
  • Fatigue and exercise intolerance
  • Weight loss and decreased appetite
  • Swollen abdomen from fluid accumulation

Cats may display more subtle signs, such as coughing, vomiting, or sudden collapse. Unfortunately, heartworm disease is often diagnosed late, making early prevention critical.

How to Prevent Heartworm Disease:

  • Monthly Preventatives: Oral or topical medications can kill immature heartworms before they develop into adults.
  • Annual Testing: Even pets on preventatives should be tested yearly to ensure they’re protected.
  • Reduce Mosquito Exposure: Limit outdoor activity during peak mosquito times and eliminate standing water around your home.

Treatment for Heartworm Disease

If your pet contracts heartworm disease, treatment can be lengthy and expensive. Dogs require injections to eliminate adult worms, while cats often receive supportive care since no approved treatment exists for feline heartworm disease.

Prevention is far more effective and affordable than treatment. Protect your pet by staying consistent with their preventative care.
