Kill fleas, ticks and mosquitoes through contact.

Why are little bites a big deal?
When fleas, ticks and mosquitoes bite your dog, they can cause irritation and transmit deadly diseases. Oral and chewable products don't kill fleas and ticks unless they bite your dog. K9 Advantix II doesn't require a bite to die - no biting required.
Do not use on cats.

If your dog shares your lifestyle — whether hiking in the woods, walking in the neighborhood or lounging by the TV on Sunday afternoon — choose K9 Advantix II. Just one K9 Advantix II treatment helps protect your dog from fleas, ticks And mosquitoes for 30 days. Frontline Plus offers no mosquito protection.*
Better yet, unlike oral products such as NexGard, Bravecto, and Comfortis, K9 Advantix II does not require a prescription or a bite from fleas or ticks to die.
Do not use K9 Advantix II on cats.
