Advantage for Puppies and Small Dogs up to 4kg is a monthly spot-on flea treatment available in 4-pack and 6-pack sizes. It kills fleas on contact without requiring them to bite, making it a fast-acting option for the smallest and youngest dogs.

Imidacloprid kills adult fleas within 20 minutes of application and stops re-infesting fleas from biting within 3–5 minutes. The formula also kills flea larvae in the dog's environment and reduces the incidence of flea allergy dermatitis. Water-resistant, and safe for puppies from birth and for pregnant and lactating dogs. Also treats and controls biting lice.

Puppies and small dogs spend more time being held and sitting on laps, which makes fast flea knockdown important for the whole household. Advantage's from-birth suitability means flea control can start earlier than most other products allow.
