Only K9 Advantix offers this kind of protection against biting - it stops biting fleas within 3 to 5 minutes. If that isn't impressive enough, this once-a-month topical provides your pup with more than flea control, also repelling and killing ticks and mosquitoes. K9 Advantix is safe for puppies seven weeks of age and older and is available in 4 different dosage sizes, depending on the size of your pet, remaining effective even after contact with water, when swimming or bathing.

K9 Advantix is so effective because it combines two proven ingredients, imidacloprid and permethrin, which each affect parasite nerve cells at different sites, rapidly debilitating, paralyzing, and killing parasites by acting on their central nervous systems. Imidacloprid also kills 98 - 100 percent of fleas within 12 hours.
