Dogs don't choke each other, do they? Nor do they hit each other with rolled-up newspaper, or rub each other's noses in their poop. They bite each other. A prong collar imitates a bite, but is designed NOT to penetrate. It tightens only about an inch and no more. It distributes pressure evenly all around the neck, not on one point. It's like if someone comes up behind you and pokes you in the ribs with their fingertips. It makes you jump but you don't bleed. It gets your attention. Training a dog is about communicating, not control. With a prong collar you can communicate with your dog. But it takes a knowledgeable instructor to teach you how.
