Our vision:
A world without heartworms.
More than a million pets in the U.S. have heartworms. But heartworm disease is preventable.
True to its mission of leading the veterinary profession and public in understanding heartworm disease, the American Heartworm Society sponsors heartworm education and research.
Program Details Announced for Triennial Heartworm Symposium
The American Heartworm Society has released the program for the upcoming Triennial Heartworm Symposium. This scientific meeting, to be held September 4-7, 2025, in Fort Worth, Texas, takes place just once every three years and is the only scientific symposium in the U.S. dedicated solely to heartworm disease. With scientific speakers and clinicians from around the globe presenting the latest on everything from diagnostic techniques to transmission trends to treatment protocols, the program provides a rare opportunity for practitioners to gain both scientific and practical knowledge about one of veterinary medicine’s most troublesome diseases.
Early bird rates are available until July 15th and discounted hotel rates are available on a first-come-first-served basis following registration.
The title of the 2025 symposium is “Advancing Science, Exploring Applications.”

The American Heartworm Society (AHS) has published an updated version of their Canine Heartworm Guidelines on heartworm prevention, diagnosis and treatment. The update, available on the AHS website at heartwormsociety.org, was recently completed after a thorough scientific review by a team of authors from the fields of parasitology, cardiology, and clinical practice. The revisions to the AHS Canine Guidelines were based on the latest research and understanding of heartworm management. They also address FAQs posed to the AHS by veterinary professionals like you.
