Now pet owners have an effective and affordable option for flea and tick control in an easy-to-use eight-month collar. Seresto combines two active ingredients, imidacloprid and flumethrin, providing dual action against fleas and ticks. Bayer's sustained release technology provides continuous protection over 8 months. For dogs and puppies 7 weeks of age and older.
We have several dogs that we use this on and these collars work great. We have a standard Collie that has flea allergy dermatitis and the topical flea preventatives were not working on her. Now that she has the collar on, she is flea free and her hair has grown back.
