Powerful Vet-Recommended Flea, Tick & Mosquito Protection for XL Dogs

Shield your extra-large dog from irritating pests with K9 Advantix II Flea, Tick & Mosquito Treatment. Specially formulated for dogs weighing over 55 lbs, this powerful, broad-spectrum topical treatment kills and repels fleas, ticks, mosquitoes, biting flies, and lice on contact.
