The Free Spirit Bark Collar is used to subdue excessive barking by emitting a shock correction that increases after each bark until the barking stops. When your dog barks, the collar emits a shock correction at the lowest level. The collar continues to analyze your dog's behavior and will automatically raise or lower the intensity to the appropriate level until the dog stops barking. With 15 levels it will fit most dog's temperament. Replaceable 6V Battery Included.
