How Do Dogs Get Heartworm Disease?

What Is Heartworm Disease in Dogs?

Heartworm disease is a serious—sometimes fatal—disease caused by parasitic worms that grow in a dog’s heart, lungs, and arteries.

Heartworm disease can be easily prevented in dogs but it is unfortunately quite common, affecting at least a million dogs in the U.S. While heartworm disease in dogs is treatable, it can cause serious and lasting damage.
