FRONTLINE Plus for Dogs is a waterproof, fast-acting, and long-lasting topical solution designed to eliminate fleas, flea eggs, flea larvae, chewing lice, and ticks. Formulated with fipronil and (S)-methoprene, it disrupts the flea life cycle by targeting adult fleas, eggs, and larvae, ensuring effective prevention against future infestations. This trusted product has been relied upon by pet owners for more than two decades. Suitable for puppies as young as eight weeks old, weighing between 23 and 44 pounds, FRONTLINE Plus is simple to apply. Once applied to a single spot, the treatment spreads across your dog's body, depositing in the sebaceous glands. These glands act as reservoirs that continuously release the medication, even after your dog gets wet. A single dose provides 30 days of protection against fleas and ticks. For optimal results, treat all pets in your household monthly to maintain control over fleas and ticks and prevent new infestations.
