The Pet Corrector™ emits a hiss of compressed gas which produces a broad spectrum sound (white noise) varying from a low frequency rumble to a high frequency hiss to interrupt a dog’s unwanted behaviour. The overall effect is to grab the attention of a dog. Dogs exhibit a wide range of reactions according to their hearing sensitivity and prior conditioning. The Pet Corrector interrupts many unwanted behaviours but is most often used for the following:*Barking *Jumping up *Stealing food *Chasing *Place avoidance. An essential combination tool with reward-based training methods.
