Snakes, insects and birds such as geese use the hiss sound to drive off predators, and our domesticated pets have the same sensitivity to this sound.
The Pet Corrector emits an inert gas (like fresh air), which mimics this hiss sound to interrupt undesirable behaviour. Situations in which the Pet Corrector can be used will of course vary, though key uses can include unwanted barking, jumping up, stealing food, place avoidance and aggression.
The extra tough Kong for power chewers, the King Kong claims to be the World's strongest rubber toy and is used worldwide by police and military dogs as well as competitive trainers. This extra tough version is available only in the larger sizes and shares the same hollow centre as the regular Kong so that treats and snacks can be inserted as a boredom breaker.
