Distract your dog from unwanted behaviour with Pet Corrector. This handy tool emits a hiss of compressed gas, with a broad spectrum of sound (white noise) varying from a low frequency rumble to a high frequency hiss, that will grab your dog’s attention. Almost all dogs react to Pet Corrector because the sound, reminiscent of the hiss of a snake, an angry swan, or the buzz of a dangerous insect, is genetically programmed to be associated with danger.
