Check-Chokes are a limited-closure choke chain combined with a standard collar. The Check-Choke is designed to offer pet owners an alternative to the alternative training collar or chain collar. The way this works is that the dog should react to the crisp sound of the chain. The nylon section of the collar is created to reduce the loss of neck hair and eliminate matting for long-haired coats. The unique Limited closure prevents the choke from becoming too tight.
