Eliminate the hassle of administering monthly preventives or dealing with messy topical treatments with the Seresto Flea and Tick Collar for Large Dogs. This non-greasy, odorless collar provides protection against fleas and ticks for a continuous 8 months. According to Elanco USA, this easy-to-wear collar is the #1 vet-recommended flea and tick collar, trusted by both dog parents and veterinarians.
Seresto Collar for Over 18 lbs Dogs kills and repels fleas and ticks through contact, ensuring your dog is protected from painful bites. Its innovative polymer matrix technology enables the controlled release of the active formula (imidacloprid and flumethrin) over a prolonged period, providing sustained protection. Additionally, this long-lasting collar for dogs is water-resistant. It stays effective after swimming, exposure to rain or bathing.
Seresto Collar for Dogs contains imidacloprid and flumethrin as active ingredients. The collar's innovative polymer matrix stores these ingredients inside the collar. After application, the active formula is slowly released from the site of direct contact over the dog's skin surface, from head to toes, including the tail. As the active ingredients wear off, a new supply of the active formula is continuously replenished for 8 months.
Imidacloprid controls flea infestations, whereas flumethrin repels and kills ticks. The product label suggests that the collar kills existing fleas on dogs 24 hours after the first application. It kills new fleas on the dog within two hours post-24 hours and protects against further flea infestations for 8 months.
It begins preventing new tick infestations at 48 hours after application. The collar repels and/or kills any new ticks on the dog within 6 hours after 48 hours of application.
