How to Prevent Heartworm Disease

Tick-Borne Diseases

The good news is that most dogs with heartworm disease can be successfully treated, usually with drugs (adulticide, microfilaricide) that kill adult heartworms and their offspring. But prevention is the best cure—it's safer, less expensive, and better for your pet!

Preventive medications are extremely effective and when given properly, on a regular basis, can prevent your pet from contracting heartworm disease. But remember, year-round heartworm protection is only as good as your diligence in remembering to give your pet the prescribed medication, as directed by your veterinarian!

Can I get heartworm from my pet?

Mosquitoes transmit heartworms, not pets. Humans are unnatural hosts for heartworms, therefore cases of infection are rare. Many heartworm preventive medicines for pets do eliminate other parasites such as hookworms and roundworms. Parasitic infections that can be transmitted from animals to humans are known as parasitic zoonoses.
