1. The pinch collar allows you to give the dog a gentle correction
"To use a shock, pinch or choke collar as an effective dog training method you will need:
Most people assume that the pinch collar works as a negative reinforcer or as a punishment because it causes a sensation of pain. Those who can't stand the thought of inflicting pain on their beloved dog therefore refuse to use a pinch collar. Those who see their dog as a willfully disobedient and defiant adversary or those who are angry with the dog, those who have for the moment forgotten their love for their dog, are often too willing to use pain as a motivator and assume the more the better, thus use the pinch collar harder than necessary, often with adverse results. Those who love their dog but recognize that the contrast between pleasant and unpleasant results of the dog's right or wrong response to a given stimulus greatly aid the dog in learning will generally read their dog well enough to use a pinch collar well, even though they believe that it works because it hurts.
It is my belief that the true power of the pinch collar is the similarity in the sensation it makes when popped and released to the sensation made by the mamma-bitch briefly grabbing the whelp by the neck with her teeth. Thus the impact on the dog is through his social psychology by making the statement , rather than through his self-preservation psychology by causing pain. Since the bitch rarely bites the puppy's neck very hard , it should not be necessary to give more than a moderate pop on the pinch collar, and indeed for the most part I find that a light to moderate "pop" is all that is needed. Only if the dog is quite excited with his attention intensely focused on some object or activity, thus dull to perceiving other sensation, would a stronger jerk be needed in order for the dog to notice it and respond. Thus an appropriately guaged pop will gain the dogs respect for the leadership of his handler and will impress him that the behavior in which he was engaged is disapproved, but it should not make him feel fearful. I hope the recognition that one does not necessarily need to inflict severe pain on the dog will encourage those of you who have heretofore been unwilling to use this useful device to try it --- especially if your training mentor advises you to do so and is willing to supervise your first few attempts.
3. The pinch collar can hurt a dog if it is not used properly
MEDIUM Herm Sprenger Steel Force Pinch Training Dog Collar #6421
Of all the tools used in dog training, perhaps none is more widely misunderstood and maligned than the prong collar (also known as the pinch collar). Many well-meaning but misinformed people assume that judging by its looks, the prong collar is a barbaric device intended to "stab" a dog's neck in order to correct misbehavior. While walking my own dogs on this type of collar I have encountered complete strangers who think nothing of telling me how cruel I am to use such a harsh device. While I am indifferent to this type of comment, I worry that similar incidents will drive responsible dog owners away from using this excellent, effective and kind (yes, kind) training tool on dogs that benefit from it the most. This article is meant to reassure those who are already using the collar or are considering it and more importantly, to educate those who think it is "cruel" or unfair to the dog. Each dog is different and you have to be a little more forceful with some. The dog is more sensitive high up on his neck because there is less muscle. I put my pinch collars right below the dog's ears on stubborn dogs. Initially, however, I like to let the dog get used to the collar before applying pressure. If the dog is wearing a regular collar, I put the pinch collar in front. You have to check frequently to be sure the prongs aren't catching on the regular collar. It won't work if they do.
