Sentinel flavored tablets for dogs are designed to protect dogs against heartworm disease when given monthly. The oral chew also treats intestinal parasites like roundworms and inhibit flea infestations in dogs. The beef-flavored tablets are highly effective in inhibiting the juvenile stages of heartworms and prevent the fatal disease. It also treats various internal and external parasites including whipworms, hookworms, roundworms and fleas. By eliminating the intermediate stages of the flea life cycle, it prevents flea re-infestations.
Sentinel contains Lufenuron as an active ingredient. Lufenuron, the active ingredient is an Insect Development Inhibitor (IDI), which blocks the reproduction of parasites like fleas and thus reduces the chances of re-infestations. The chew is administered as a single mealtime dose and remains effective for a span of 30 days. Easy to administer, this oral treatment is like a treat for dogs and is safe for 8 weeks and older puppies, dogs and pregnant females.
