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.
Imidacloprid, Flumethrin.
| Dog Size | Dog Weight (lbs) | Collar Length inch (cm) | Flumethrin Strength (% by weight) | Imidacloprid Strength (% by weight) |
| Small Dogs | Up to 18 | 15.0 (38) | 4.5 | 10.0 |
| Large Dogs | Over 18 | 27.5 (70) | 4.5 | 10.0 |
This collar is for external use on dogs only. Do not use it on humans or other animals. People with sensitivity to the active ingredients of the collar should avoid contact with the collar. Wash your hands thoroughly after handling the collar. Keep it away from children.
Do not use the collar on puppies under 7 weeks of age. Consult a veterinarian before using it on debilitated, aged, breeding, pregnant, or nursing dogs. If your dog is on other treatments, talk to your vet before using this collar.
Do not attach a leash to the collar, as this may cause breakage. Keep the collar in the protective bag and in the outer packaging until use. The collar contains small parts and can be a choking hazard. Store it out of reach of children and pets. Ensure that the collar is not fitted too tightly.
To maintain an eight-month efficacy, do not bathe dogs more than once per month. For dogs that swim once per month or more, the control duration is reduced to five months for flea control and 7 months for tick control.
