Advantage Red for Large Dogs 10–25kg is a monthly spot-on flea treatment that kills fleas on contact — no biting required. The red pack covers the large-dog weight tier and suits households where flea control is the primary concern.

Imidacloprid kills adult fleas on contact within minutes and stops re-infesting fleas from biting within 3–5 minutes. The formula also kills flea larvae in the dog's surroundings and reduces flea allergy dermatitis. Water-resistant once dry, and safe for puppies from birth. Also controls biting lice.

Advantage handles flea control without bundling tick or worm treatment, which suits owners who prefer to manage each parasite category with a separate product. The colour-coded weight-tier packs make dosing straightforward in multi-dog households.
