Description
The Seresto flea and tick prevention collar is a long-lasting, effective option for preventing fleas and ticks on large dogs. The collar is designed to release a low dose of active ingredients over an 8-month period, providing continuous protection against fleas, flea eggs, flea larvae, ticks, and lice. The active ingredients are imidacloprid and flumethrin, which are both effective at killing and repelling fleas and ticks. The collar is waterproof and can be worn during bathing, but it should be removed before swimming or allowing the dog to submerge in water for extended periods of time.
