Heartgard Plus Brown Pack - Heartworm Chewable for Large Dogs 22-45lg (51-100 lbs)

Heartgard Plus for large dogs (51-100 lbs) is a highly palatable tablet that prevents heartworm infection in dogs. This beef-flavored chew works to eliminate heartworm larvae and remains effective for a month; which is why it is the #1 choice of all vets. Additionally, Heartgard Plus brown pack also helps to control roundworms and hookworms and is safe to use for puppies older than 6 weeks of age.

Heartgard Plus Chewable (51-100 lbs) is given orally for prevention of heartworm infection. It is effective against larval stage of the worms and thus prevents development of the adult stage. The recommended doses should be administered for an effective course of treatment each month. Heartgard Plus contains a powerful combination of active ingredients; Ivermectin and pyrantel that works as a strong multi-parasitic treatment and eliminate all the immature heartworm larvae including intestinal roundworms and hookworms.

Heartgard Plus (Ivermectin and Pyrantel) Heartworm Treatment for Large Dogs

Heartgard Plus contains two active ingredients, Ivermectin (272 mcg) and Pyrantel (227 mg). Ivermectin is anti-parasitic, which treats multiple parasite infections and pyrantel is a strong anthelmintic. Together these compounds control the nerve impulses that flow through the neurological system of the worm, thus causing paralysis. The paralysis causes the death of the worms which are then removed from the body.
