Our mission is to remove Heartworm disease as a barrier to adoption for dogs from Montgomery County animal shelters by working with adopters and other nonprofit rescues to supply treatment.

Be a Heart Hero

Thousands of homeless dogs enter our local shelter every year, and up to 40% of them are Heartworm Positive. A Heartworm Positive dog is 75% less likely to be adopted than a Heartworm Negative dog. Heart Heroes provide hope for the Heartworm Positive dogs who are looked over by adopters and rescues everyday, at no fault of their own. 

Provide ongoing hope and become a monthly Heart Hero today by donating to

The Heartworm Foundation through the PayPal Giving Fund.

Our Program

The Heartworm Foundation offers slow kill for all dogs in Montgomery County. Shelter dogs are treated for free and community dogs are treated at a low cost. Shelter dogs receive a free exam, a Heartworm test and 6 months of Heartworm preventative. If your dog is Heartworm positive we also include doxycycline and we ask adopters to purchase an additional year of Heartworm preventative at cost.
