Product description

Size:21-55 lb  |  Style:2 doses

Flea, tick and mosquito bites can be very painful for your dog. Worse, those bites may expose your dog to irritation, itching and even deadly diseases. Fleas may cause Flea Allergy Dermatitis (FAD) and if ingested, fleas could cause tapeworms. A bite from an infected tick can transmit diseases, such as Lyme disease or Rocky Mountain spotted fever, to your dog. And mosquitoes may transmit heartworms* or even West Nile virus to your dog.

K9 Advantix II is a veterinarian-recommended monthly flea, tick and mosquito treatment for your dog that kills through contact. No biting required.

Did you know not all flea and tick products work the same way? Frontline Plus doesn’t mention mosquitoes anywhere on the package. Chewable products require fleas and ticks to bite in order to die. Do not use on cats. *K9 Advantix II should not be used in place of a heartworm disease prevention product.

Do not use on cats.

*K9 Advantix II should not be used in place of a heartworm disease prevention product.
