Jeff Frawley discusses the differences between our wide variety of prong collars and more importantly, how to properly fit a prong collar on your dog. Prong collars do not apply pressure to the dogs trachea, making them a safe alternative to a slip collar, and much safer than allowing your dog to pull into a flat collar which can cause permanent damage to the dogs wind pipe. Instead a prong collar tightens, creating a pinching sensation that is instantly released once the dog “yields to the leash” or stops pulling.
