The Pet Corrector Stops: Barking, Chasing, Stealing, Jumping Up and Place Avoidance. It works by emitting a hiss of compressed gas to interrupt a dog’s unwanted behavior. This distracts the dog and allows the dog owner or trainer to insert a positive command such as “sit” or “down” and reward accordingly. It is used and recommended by trainers and behaviorists throughout the world. Made by The Company of Animals USA.
