The prohibitive cost to treat this fatal disease is usually between $300 and $500 per animal.  Humane Educational Society tests and treats dogs for heartworm disease.  At some shelters, these dogs would not be given a second chance.  Thanks to donors who give to our Special Needs fund, we can continue to treat these perfectly wonderful dogs.

Heartworm disease is a serious and potentially fatal disease in pets in the United States and many other parts of the world. It is caused by foot-long worms (heartworms) that live in the heart, lungs and associated blood vessels of affected pets, causing severe lung disease, heart failure and damage to other organs in the body.  
Heartworms are transmitted by an infected mosquito.  When an infected mosquito bits a pet, the infective larvae are deposited onto the surface of the animal's skin and enter the new host through the mosquito’s bite wound.
