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.

What's a Like New item?

Like New products are often unused returns, or demo models from retail locations that just can't be sold as brand new anymore. The item may be missing the original packaging, or in the original packaging but not sealed. The item may also be a new, unused item with defects. See the seller’s listing for full details and description of any imperfections.

Some of the products may have never even been powered on, but have merely been removed from their packaging at some point. As a result, these products are heavily discounted even though you can expect them to function as if they were new.
