Heartgard Plus Chewables for Dogs - Heartworm Prevention

Heartgard Plus are beef flavored tasty chewables with anthelmintic properties. They are used for treating roundworms and hookworms and for preventing heartworms in dogs. The monthly treatment saves the pet from heartworm diseases by destroying the tissue stage of heartworm larvae. It may not suit border collies due to the presence of Ivermectin in it.

How it works?

Heartgard Plus are beef flavored chewables for preventing heartworms found in puppies and dogs. The monthly administered tasty chewables treat heartworm infection by killing tissue stage of the heartworm larvae. Available for all sizes of dogs, these tablets protect the pet from all kinds of heartworm diseases.

Ivermectin and Pyrantel are the active ingredients that act as perfect heartworm preventives and destroy immature stages of heartworms. The tablets with anthelmintic properties are also an effective treatment for killing and controlling roundworms and hookworms.


Nuheart is a generic alternative of Heartgard. With the same effectiveness of Heartgard, the oral chew protects dogs from harmful heartworm disease. It contains Ivermectin, which effectively destroys heartworm larvae and prevents the parasitic infestation. This generic version can be used on puppies 6 weeks of age and older.

Kindly note that as Merial is now part of Boehringer Ingelheim, the manufacturer’s name may differ on the product packs according to the stock availability.
