Advantage Blue for Extra Large Dogs over 25kg is a monthly spot-on flea treatment for the largest weight tier. It kills fleas on contact without needing them to bite, providing fast-acting protection for giant and extra-large breed dogs.

Each pipette delivers imidacloprid at the dose calibrated for dogs over 25kg. The formula kills adult fleas on contact, stops re-infesting fleas from biting within 3–5 minutes, and also targets flea larvae in the dog's environment. Water-resistant and also controls biting lice. The extra-large tier ensures giant breeds receive a properly calibrated dose.

Extra-large dogs accumulate more flea exposure through their coat surface area and outdoor time. A dedicated weight-tier product ensures consistent protection without the guesswork of doubling up on smaller doses.
