Heartworm disease is a serious and potentially fatal parasitic infection that affects dogs around the world. Caused by the parasitic roundworm Dirofilaria immitis, heartworm infection can lead to severe damage to the lungs, heart, and other organs. Heartgard is a widely used and highly effective heartworm preventive medication that plays a crucial role in protecting dogs from this devastating disease.
The American Heartworm Society (AHS) estimates that over 1 million dogs in the United States are infected with heartworms. The infection is spread through the bite of an infected mosquito, which transmits infective larvae (microfilariae) into the dog's bloodstream.
Heartworm disease can progress through various stages, each with increasingly severe consequences. The microfilariae mature into adult worms that reside in the dog's heart and pulmonary arteries. Over time, these worms can cause:
Heartgard is a monthly chewable tablet that contains the active ingredient ivermectin, which effectively kills heartworm larvae and prevents adult worms from developing. Regular administration of Heartgard provides numerous benefits:
Heartgard is available in various formulations to accommodate different dogs' needs:

Consult your veterinarian to determine the appropriate formulation for your dog.

Based on your dog's weight, calculate the correct Heartgard dose using the chart or veterinarian's recommendation.
