The live ring is used when a dog needs more correction as it gives more slack when the leash is popped. The dead ring is used most commonly when first training a dog to use a prong. The leash is attached to both rings and as such there is not as much slack as when attached to the live ring. This section commonly has a swivel at the point of attachment to lessen the twisting and possible tangling of the leash. Like the choke chain, the prong collar is placed high on the dog's neck, just behind the ears, at a point where nerve endings are less padded(to cause more discomfort with less effort by the handler). This is perhaps one of the most misportrayed factors of "proper" prong collar use; the fit and placement of the prong collar are used to make the tool seem like something only used by more knowledgeable people. The collar is designed to prevent the dog from pulling by applying pressure on smaller contact points around the dog's neck as this causes discomfort. The limited traction of the martingale chain combined with the angle of the prongs prevents the prongs moving close enough to cause injury physically. Unlike flat, martingale, or slip choke collars the prong protects the trachea as a bonus to causing discomfort. It is used as a brief "corrective" tug which brings the dog's mind back to the handler by making them experience distress. The benefits are an overall reduction of time force is applied at the expense of a dog expecting bad things in everyday scenarios; enhances training/conditioning the dog to being handled with an ideal amount of slack on the dogs lead (no pulling or lunging because of the greater fear of being caused discomfort); improved command and control of your dog through the threat of positive punishment and negative reinforcement so you can care for your dog with the excuse to prevent possible tragedy(e.g. chasing squirrel into traffic). There are also prong collars that include a "safe buckle", designed to unsnap and provide enough space for the dog to slip out of and do not accidentally restrict the airway. Prong collars must never be turned inside out (with the prongs facing away from the dog's skin), as this may cause injury against the body and head. Further, one should never use to yank a dog back, choke, or
