When they’re protected from fleas and ticks, your dog can stay focused on the unique quirks and behaviors that make them, well, your dog. Seresto^® for dogs offers the performance you expect from a monthly flea and tick treatment like topicals or pills, with the convenience of an easy-to-use 8-month collar. You read that right: One effective, odorless, non-greasy collar equals 8 months of protection.
