Fast-Acting Flea Treatment for Large Breeds

Advantage Blue for Extra Large Dogs is a veterinarian-recommended topical flea treatment designed to provide immediate relief from flea infestations. Specially formulated for dogs weighing 55 lbs (25 kg) or more, this powerful solution kills fleas on contact, stopping infestations before they can spread.

Long-Lasting Protection for a Happy, Healthy Pet

One application of Advantage Blue delivers up to 30 days of continuous flea protection, ensuring your dog stays comfortable and itch-free. It not only eliminates adult fleas but also prevents reinfestation by disrupting the flea life cycle.

Easy, Waterproof, and Mess-Free Application

Designed for convenience, Advantage Blue is applied topically between the shoulder blades, quickly absorbing into the skin for effective, non-greasy protection. Its waterproof formula remains effective even after bathing or swimming, keeping your dog protected in all conditions.
