Advantage II Large Dog Vet-Recommended Flea Treatment & Prevention for Dogs 21–55 lbs | 4-Month Supply

Keep your dog protected from irritating fleas with Advantage II Large Dog Vet-Recommended Flea Treatment & Prevention, a fast-acting topical flea treatment specially designed for large dogs weighing between 21 and 55 pounds. This veterinarian-recommended formula delivers powerful flea protection by killing adult fleas, flea larvae, and flea eggs through contact, helping to break the flea life cycle and prevent future infestations.

The easy-to-apply monthly treatment starts working within hours and provides long-lasting protection for up to 30 days per application. With this convenient 4-month supply, pet owners can ensure continuous flea defense without frequent repurchasing. Unlike oral treatments, Advantage II works externally and does not require fleas to bite your dog to die, offering quick relief from itching, scratching, and discomfort.

Its waterproof formula remains effective after bathing or exposure to rain once fully dried, making it ideal for active dogs. The fragrance-free solution is gentle on dogs while providing reliable protection against flea infestations that can affect your pet’s comfort and overall health.

Perfect for households with multiple pets or dogs that spend time outdoors, Advantage II helps maintain a cleaner, healthier environment by reducing flea populations in your home. Trusted by veterinarians and pet owners alike, this flea prevention treatment is an essential part of your dog’s regular wellness routine.
