This training collar is made of chrome-plated steel that is welded for strength and resistance to rust, tarnish, and breakage. Its prong links use a link closure style, so the collar can be unfastened and refastened around the dog's neck for easy on-and-off handling. The prong design is intended to distribute correction pressure evenly around the neck as part of a structured training routine. Owners can adjust the overall length by adding or removing links, and vinyl comfort tips are available separately to fit over the prongs. The collar is intended for use during active, supervised training sessions such as leash walking and obedience work, and is not designed as a tie-out device. It comes in several gauge and length combinations to suit different dog sizes.
