Heartgard Plus Chewables for Dogs

Heartgard Plus for Dogs is a trusted monthly treatment designed to protect your beloved canine companion from heartworm disease. These chewable tablets are real beef-flavored, making administration a breeze for both you and your pet. Not only does Heartgard Plus prevent heartworm disease, but it also controls and treats 3 species of hookworms and 2 species of roundworms, ensuring comprehensive protection for your furry friend. With its convenient monthly dosing regimen, Heartgard Plus offers peace of mind for pet parents while promoting your dog's overall health and well-being. It is recommended for dogs 6 weeks of age and older.

How does Heartgard Plus (ivermectin, pyrantel) Chews work?

Heartgard Plus chewable tablets for dogs contain two key ingredients, Ivermectin and Pyrantel, which work together to protect your furry friend against heartworm disease and intestinal parasites. Ivermectin works by disrupting the nerve transmission in heartworms and other parasites, ultimately leading to their paralysis and death. Pyrantel, on the other hand, acts by paralyzing and eliminating intestinal parasites like hookworms and roundworms. By administering Heartgard Plus regularly, you can effectively prevent heartworm disease and control common intestinal parasites in your dog, ensuring their continued health and well-being.


Nuheart is a generic form of Heartgard. This heartwormer has the same effectiveness as Heartgard. It contains Ivermectin, which is the exact same ingredient that can be found in Heartgard. The meat-flavoured tab eliminates heartworm larvae and protects dogs from dangerous heartworm diseases. It is an affordable and highly effective heartworm preventive.
