VSVS Dog Training Collar Chain 60 cm Dog Chain Leash  (Silver)

The purpose of a slip dog collar (choke chain) is to apply pressure (negative reinforcement) or a correction (positive punishment) when a dog is "misbehaving". By popping the leash (as it is called in dog training terms) the slip collar will tighten around the dog's neck and will only release once the dog slows down, or the handler will release the pressure once the dog performs the requested exercise on the leash.
