I have been using HEARTGARD Plus for over twenty years to prevent heartworm disease and control intestinal parasites in my patients. It has been proven to not only be a safe and effective preventive, but it is also a joy to administer as it is a tasty beef chew.

Heartworm disease has been diagnosed in all 50 states.8 And just one bite from an infected mosquito can transmit this potentially deadly disease to your dog. The risk is real. That’s why vets recommend using monthly heartworm disease prevention all year long.
