If your small dog spends time outdoors, even short walks can expose them to fleas, ticks, mosquitoes, and other biting pests. K9 Advantix II Small Dog Flea & Tick Treatment is designed to provide reliable monthly protection for dogs weighing 4–10 lbs, helping your pet stay comfortable and protected every day.

This easy-to-use topical treatment works quickly to kill fleas and repel ticks, mosquitoes, biting flies, and lice before they become a bigger problem. Each box includes 6 convenient doses, giving your dog up to six months of continuous protection with simple monthly applications.
