Heartgard Plus Chewables for Dogs is a veterinarian-recommended monthly chew that helps prevent heartworm disease and treats and controls common intestinal worm infections in dogs and puppies 6 weeks of age and older.
Given once a month as a treat, the delicious, real-beef flavored chew helps prevent heartworm disease caused by Dirofilaria immitis, a serious infection that can damage a dog’s lungs and heart if left untreated.
In addition to heartworm prevention, Heartgard Plus treats and controls two species of roundworms and three species of hookworms, helping support your dog’s overall health year-round.
Heartgard Plus is formulated with two key ingredients:
When administered monthly, these ingredients work together to interrupt the parasite life cycle and help protect your dog from intestinal and heartworm infections.
Nuheart is a generic alternative to Heartgard that contains ivermectin for the prevention of heartworm disease in dogs. When administered monthly as directed, Nuheart helps eliminate developing heartworm larvae (Dirofilaria immitis) and prevents them from maturing into adult heartworms. Suitable for puppies and dogs 6 weeks of age and older, Nuheart provides reliable protection against heartworm infection.
Note: Unlike Heartgard Plus, Nuheart contains ivermectin only for heartworm disease prevention. It does not treat intestinal worms.
