Flea And Tick Prevention & Treatment For Dogs 4-10 Lbs., 4 Doses

K9 Advantix II is a veterinarian-recommended topical flea, tick, mosquito and biting fly prevention and treatment designed for small dogs weighing 4–10 lbs. This 4-pack contains four individual 1-month applications, providing convenient monthly protection against common parasites and disease-carrying insects that can affect your pet's health and comfort.

Applied directly to the skin, K9 Advantix II kills through contact—meaning fleas and ticks don't need to bite your dog for the treatment to work. The formula not only eliminates adult parasites but also prevents flea eggs and immature forms from developing into adults, breaking the pest lifecycle. After 24 hours, the formula becomes waterproof, so your dog can bathe or swim while maintaining continuous protection for up to 30 days per application.
