Advantage for Dogs 10–25kg is a monthly spot-on flea treatment that kills fleas on contact — no need for them to bite first. The 4-pack covers four months of protection for medium to large dogs, suited to owners after a dedicated flea solution without tick or worm cover.

The active ingredient imidacloprid kills adult fleas within 20 minutes of contact and also targets flea larvae in the dog's surroundings. Re-infesting fleas stop biting within 3–5 minutes and are killed within an hour. The water-resistant formula stays effective after bathing, and also treats and controls biting lice. Applied monthly to the back of the neck.

Advantage's contact-kill mechanism — fleas don't need to bite to be killed — makes it particularly suited to dogs with flea allergy dermatitis, where even a single bite triggers a reaction. The fast knockdown within minutes of contact sets it apart from products that require ingestion.
