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.
