K9 Advantix II Extra Large Dog 4-pk Blue

K9 Advantix IIis the veterinarian-recommended formula that helps defend your dog against five pests: fleas, ticks, mosquitoes, biting flies, and lice.

And unlike other treatments, K9 Advantix II kills and repels fleas, ticks and mosquitoes.

K9 Advantix II topical treatment gets straight to work killing fleas on dogs within 12 hours of initial application.

This formula stops existing flea infestations and prevents new ones by killing adult fleas on contact so they can't lay eggs, and they don't have to bite your dog to die.

This topical, spot-on formula makes application simple - going on in seconds.

It is easier than a flea collar and there are no hard-to-swallow pills.

You will also love that K9 Advantix II is fragrance-free and waterproof after 24 hours of application.

Check the product label for information on application and potential side effects.

Provides pest protection on both indoor and outdoor dogs.

Available over the counter with no prescription needed.
