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.
No state is heartworm-free
An American Heartworm Society survey of approximately 6,000 veterinary practices and shelters determined that heartworm disease continues to be diagnosed in all 50 states.
Safely transport heartworm-positive dogs
Rehoming. A move. Accompanying an owner on a trip. Such situations can mean that dogs diagnosed with heartworms must travel. The American Heartworm Society and the Association of Shelter Veterinarians recently released joint transport recommendations designed to safeguard the health of infected dogs while ensuring they do not become vectors for heartworm transmission.
How do pets get heartworms?
Heartworm disease is a devastating disease that starts with a single mosquito bite. Learn how pets get heartworms—and how heartworms can be prevented.
