Elanco | K9 Advantix II Flea & Tick for Dogs

K9 Advantix II is a convenient monthly topical application that kills and repels fleas, ticks and mosquitoes. It's specially formulated for dogs with imidacloprid, permethrin and pyriproxyfen for broad spectrum protection against these ectoparasites that can transmit diseases. K9 Advantix II is for use on dogs 7 weeks and older and weighing 4lbs. or more. K9 Advantix II kills fleas, ticks, mosquitoes and lice, and repels biting flies. And because it works through contact, there's no biting required. Repellency helps prevent ticks, fleas, and mosquitoes from attaching, biting or feeding. A repelled parasite doesn't bite or attach. If it doesn't bite or attach, it can't transmit the organisms that may cause disease. K9 Advantix II is waterproof. There is no need to reapply the product after weekly swimming or a bath.
