Max Pro Obey
Emits a Hissing Sound to Stop Unwanted Behavior!
Max Pro® Obey® is a humane audible pet training tool which corrects unwanted behavior in pets by emitting a loud hissing sound which animals instinctively know as a negative stimulus that interrupts undesirable behavior.
For all sizes and breeds-I have heard good reports on this-a bull mastiff escape artist stopped in his tracks from going under the fence when he heard the noise. A few more times and he will associate the behavior as -a not to do again, or I'll hear a scary noise.
