Our take on the K9 Advantix II Small Dog Vet-Recommended Flea, Tick & Mosquito Treatment & Prevention | Dogs 4-10 lbs.

K9 Advantix II Small Dog is a topical flea, tick, and mosquito treatment for dogs weighing 4–10 lbs. It kills adult fleas on contact within 12 hours and also repels and kills ticks, mosquitoes, biting flies, and lice. It is vet-recommended and easy to apply, making it a convenient alternative to oral medications. However, it is toxic to cats, so households with cats must take care to keep treated dogs separate until the product dries.
