There's no mess, grease, or smell, and it comes with a specially designed safety release mechanism to provide you with peace of mind.
All Seresto Flea and Tick Control Collars are designed with a rachet-release mechanism, which enables the collar to widen should your pet become trapped. The collar also features a pre-determined breaking point that allows the collar to snap entirely if enough force is applied. Can be used on puppies from 7 weeks of age.
