Our take on the K9 Advantix II Topical Flea & Tick Treatment for Dogs 11-20 lbs

K9 Advantix II is a monthly topical treatment that kills and repels fleas, ticks, mosquitoes, biting flies, and lice on dogs 11–20 lbs. It kills fleas within 12 hours and works on contact, so fleas don't need to bite to die. The formula is fragrance-free, waterproof after 24 hours, and available without a prescription. Compared with Frontline Plus, it adds mosquito and biting fly repellency, but it is toxic to cats and must not be used on them.
