Our Program and Policies


The Heartworm Foundation's mission is to provide sponsorship for Heartworm positive dogs Montgomery County.  


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.

Eligible Rescues

Rescues will be approved by the Heartworm Foundation board. Some of the criteria considered include reputation, stability, foster base, and location. Rescues pulling a sponsored dog must be willing to take on the responsibility of seeing the dog through treatment and to its forever home. At this time MCAS fosters are not eligible to pull a sponsored dog and have it treated by The Heartworm Foundation, as legally the dog still belongs to the shelter, and is still at risk should the foster no longer be able to foster the dog.
