In the News

The American Heartworm Society is the leading resource on heartworm disease, and our mission is to lead the veterinary profession and the public in the understanding of this serious disease. Every year, hundreds of stories are written on the diagnosis, prevention and treatment of heartworm, as well as on the plight of affected pets. These stories are an important way of reaching both veterinary professionals and pet owners with information they need to know about heartworm disease.

The American Heartworm Society is led by a board of directors comprised of veterinarians and specialists in the fields of veterinary parasitology and internalmedicine. As leaders in the fight against heartworm disease, they are available as resources and authors of related stories.

Members of the media are encouraged to contact the American Heartworm Society for information, visuals and interviews about heartworm disease. Please contact Sue O’Brien at This email is for media inquiries only. All other inquiries, please email:

Dear Readers: If you have a dog, it should be on a HEARTWORM preventative medication no matter where you live. It used to be that if you lived in areas with harsh winters, you didn't have to give the pet the medication during the winter months. Now, the American Heartworm Society says you should give your pet heartworm medication all year long. The disease can still be spread by wildlife or when you travel with your pet. Pets become infected when they are bitten by mosquitoes that are carrying the parasite.
