K9 Advantix for Medium Dogs is specially formulated for dogs weighing 11–20 lbs. This aqua-pack variant contains a convenient 1.0 mL topical applicator designed to provide monthly protection against fleas, ticks, mosquitoes, biting flies, and lice.
The fast-acting formula kills fleas through contact, meaning fleas do not need to bite your dog to be affected. Easy to apply and fragrance-free, K9 Advantix helps provide reliable month-long external parasite protection for medium dogs while supporting comfort and everyday outdoor protection.
How it helps
K9 Advantix combines imidacloprid and permethrin to provide broad-spectrum external parasite protection. Imidacloprid rapidly kills fleas on contact, helping prevent flea reinfestations and reducing the risk of flea allergy dermatitis (FAD). Permethrin helps repel and control ticks, mosquitoes, biting flies, and lice. Together, these ingredients provide month-long protection against common external parasites.
Who it’s for
Medium dogs from 7 weeks of age and older, weighing 11–20 lbs
