If you are looking for an alternative to monthly topical applications of flea and tick control the 8 month Seresto collar is for you. Seresto is an easy-to-use, odorless collar that kills and repels fleas and ticks for 8 continuous months. It also aids in the treatment and control of sarcoptic mange and kills lice.
Seresto is a unique polymer matrix flea & tick collar that offers a continuous supply of two active ingredients: imidacloprid and flumethrin for effective 8-month protection against fleas and ticks. That's one convenient, non-greasy, odorless flea and tick collar instead of 8 monthly treatments.
The active ingredients are stored within the collar. They are released in low concentrations and are distributed over your dog's hair and skin surface for 8 months. As active ingredients wear off over time, Seresto for dogs continuously replenishes the skin and coat with a new supply of active ingredients. Fleas and ticks are killed through contact with the active ingredients — no biting required.
Small: Neck size up to 14".
