K9 Advantix^® is a once-a-month topical tick, mosquito and flea treatment for dogs and puppies 7 weeks of age and older. It contains imidacloprid and permethrin. It is available in 4 dosage sizes: 10 lbs. and under, 11-20 lbs., 21-55 lbs., and dogs weighing over 55 pounds. It is available in both 4 packs and 6 packs.

Nothing else offers this kind of triple protection against biting insects.

A synergistic effect that enhances efficacy.
K9 Advantix^® is a unique combination of two proven ingredients that work synergistically against parasites. The mode of action of imidacloprid complements the activity of permethrin. Each affects parasite nerve cells at different sites. When combined, the neurotoxic effect against parasites is enhanced. This leads to rapid paralysis and death of the parasites.

Prevents mosquitoes from biting.
New K9 Advantix repels and kills mosquitoes before they can bite – protection Frontline® Plus can’t offer. As the vector of West Nile Virus, mosquitoes are a growing concern. Research demonstrates K9 Advantix kills up to 98.3% of mosquitoes and reduces their feeding up to 95.2%.¹ Mosquitoes that don’t bite can’t annoy dogs or transmit disease.

Keeps ticks from biting.
New K9 Advantix^® offers superior protection against ticks because it repels and kills Deer ticks, American dog ticks, Lone Star ticks and Brown dog ticks before they can attach. It repels up to 98.5% of ticks–repellency Frontline® Plus can’t offer.² Ticks that are repelled and die without biting can’t spread disease.

Stops fleas from biting.
New K9 Advantix^® offers the superior protection against fleas you can only get from imidacloprid. It stops fleas from biting in less than 5 minutes and kills them before they lay eggs.³ K9 Advantix also kills flea larvae before they develop into more biting fleas, so there’s no need for an IGR.

Protects dogs young, old, small and tall.
New K9 Advantix is gentle enough for puppies 7 weeks of age or older and dogs of any size. Just apply topically once a month to protect dogs from the problems of biting ticks, mosquitoes and fleas.

Keeps working after swimming or bathing.
K9 Advantix remains effective after swimming or bathing. After repeated swims,
it kills 97.9-100% of ticks and 92.5-100% of fleas. After bathing, it kills 97.4-100% of ticks and fleas.⁴ You can recommend it with confidence for dogs who like water.
