K9 Advantix topical flea, tick & mosquito treatment for small dogs 4–10 lb — 2 monthly waterproof doses, contact-kill

K9 Advantix Small Dog is a topical monthly flea, tick and mosquito treatment formulated for dogs 4–10 lbs that kills and repels pests on contact.

Designed for small dogs at least seven weeks old, this two-treatment pack delivers a 30-day topical protection per application against fleas, ticks, mosquitoes, biting flies and lice. The formula acts through contact so parasites don’t have to bite to die, and it begins to stop existing infestations within about 12 hours. Applied to the skin between the shoulder blades, each dose is fragrance-free and becomes waterproof after 24 hours, giving hands-off protection that fits a busy household.

How quickly will K9 Advantix stop a flea problem?

After the first monthly application, K9 Advantix works rapidly by contact to reduce adult flea numbers and interrupt the pest life cycle. Many dogs experience measurable reduction of active fleas within 12 hours, with continued control as the month progresses when used as directed.
