The Pet Corrector (PC) is a convenient, portable interrupter of undesirable behavior, that provides a warning hiss stimulus. Dangerous snakes, insects and birds like geese use the hiss sound to drive off predators like wild dogs, cats or horses, and our domesticated pets have the same sensitivity to sound. It is important that the PC is used cautiously and responsibly, so as not to traumatize or frighten your pet. The gas is inert and like fresh air, cannot cause physical harm. The Pet Corrector emits a blast of compressed air, ideal for interrupting undesirable behaviors. Ensure that you reward immediately after the behavior has ceased. A free training guide is included with helpful tips and key do's and don'ts.
