Trifexis 560 mg 21-40 lb 6 monthly doses

Trifexis is a monthly chewable tablet for dogs that kills fleas, prevents heartworm disease and treats and controls adult hookworm, roundworm and whipworm infections. Trifexis combines two trusted active ingredients to provide protection for your dog against these three kinds of dangerous parasites. Trifexis is beef-flavored, so you can offer it as a treat. And, because Trifexis is given orally, you don't have to isolate your dog from other pets or children.
