K9 Advantix II is a topical treatment designed to protect dogs against fleas, ticks, mosquitoes, lice, and stable flies. It works through contact, killing parasites without the need for them to bite, which reduces the risk of allergic reactions and disease transmission. This product kills adult fleas, eggs, and larvae, as well as ticks and mosquitoes, while also repelling biting insects. It remains effective even after water exposure, once dry. Indicated for dogs and puppies over 8 weeks of age. Do not use on cats.
