Sentinel Flavor Tabs: Oral Parasite Treatment for Dogs

Sentinel Flavor Tabs contain milbemycin oxime and lufenuron as active ingredients. Milbemycin oxime is an anthelmintic that eliminates the tissue stage of heartworm larvae and the adult stage of hookworm, roundworm, and whipworm infestations when administered as recommended.

Lufenuron is an insect development inhibitor that breaks the flea life cycle by inhibiting egg development. It prevents most flea eggs from hatching or maturing into adults and thus prevents and controls flea populations by breaking the life cycle.
