This collar is somewhat frightening in appearance, but is actually quite humane. It is a collection of blunt hooks, that, when activated, gather the skin around the dogs neck and create a pinching effect. It is much safer than a choke collar and easier for novice trainers to use effectively. The pinch collar helps your dog learnt to accept responsibility for his behavior choices, but unlike the head collar is a complete non entity to the dog unless he is misbehaving.
