The purpose of the pet corrector is to gain the dog's attention in the instant they are exhibiting an unwanted behaviour. It helps to stop barking, chasing, stealing, jumping up, place avoidance and other unwanted behaviour. It works by emitting a hiss of compressed gas to distract the dog and the owner can then insert a positive command and reward. It is used and recommended by trainers and behaviourists throughout the world. Comprehensive training instructions are included to ensure the correct use.
