How does K9 Advantix® II work?
Easy flea and tick drops for dogs
K9 Advantix® II goes on in seconds; apply drops directly on your dog's skin. (See product label for complete directions for use.) It kills fleas on dogs within 12 hours — half the time of other leading topicals* — and continues providing triple-pest protection all month long.
*Based on label claims.
Includes mosquito repellent for dogs
Unlike most competitors, K9 Advantix® II is more than flea and tick prevention for dogs. It also kills and repels mosquitoes that may transmit heartworm disease. Swampy or wet areas are no problem either. K9 Advantix® II is waterproof after 24 hours and stays that way for 30 days.
Vet-recommended* flea and tick prevention for dogs
No prescription needed. K9 Advantix® II is effective on dogs and puppies 7 weeks of age and older that weigh 4 or more pounds. Vets love how K9 Advantix® II is effective against deer ticks, American dog ticks, brown dog ticks and Lone Star ticks.
Protection for large and small dogs
K9 Advantix® II comes in different strengths and dosages to best fit your furry friend. Whether your pet is a gentle giant or fun-sized, K9 Advantix® II provides convenient flea, tick and mosquito prevention for dogs of all sizes.
