Sentinel Flavor Tabs Yellow is a comprehensive 5-in-1 treatment that protects dogs from five different kinds of parasites. With just one monthly dose, these tablets ensure your canine friend is safe from fleas, heartworm disease, and three types of intestinal worms. Lufenuron, one of the active ingredients in Sentinel, prevents flea eggs from hatching or maturing, breaking the flea life cycle and controlling flea populations.
Prescribed for over 20 years, Sentinel for Medium Dogs comes in tasty pork, liver-flavored tablets that dogs love, making administration easy and convenient. Sentinel is safe for use in puppies as young as 4 weeks of age, allowing you to start parasite protection early. Sentinel flea and heartworm tablets are available in four different weight-specific packs, ensuring a perfect fit for dogs of all sizes.
Sentinel monthly flea and worm tablets for dogs contain active ingredients lufenuron and milbemycin oxime. Lufenuron works as an insect growth inhibitor. After a bloodmeal, the female flea ingests lufenuron that is deposited in its eggs. It prevents the majority of flea eggs from hatching or maturing, thus breaking the flea life cycle and preventing and controlling flea populations.
Milbemycin oxime interferes with invertebrate neurotransmission. It eliminates the tissue stage of heartworm larvae as well as the adult stage of hookworm, roundworm and whipworm infestations when administered as indicated on the label.
As per studies using experimental flea infestations referenced in the label, lufenuron delivered more than 95% control of flea egg development with a single dose.
