Sentinel is a flea treatment and dewormer for dogs that kills fleas and larvae, controls intestinal worms (hookworm, tapeworm, roundworm, and whipworm), and prevents heartworm disease. It also helps treat flea allergy dermatitis and works for up to a month with each dose. Sentinel comes in a chicken-flavoured dog chew that can be given to your pet directly like a treat or added to your dog’s food. Since it’s not a topical treatment, you don’t have to worry about your dog accidentally rubbing the solution off or going into the water after application!
