Pet Pals ZA1513 14 19 GG Nylon Martingale Collar 14-20 In Blue

Guardian Gear Nylon Martingale Collars are a great alternative to traditional choke chains! These all-nylon collars work just like a choke collar. They tighten when a dog pulls, and relax when a dog stops pulling.
Works like a choke collar but without the chain. All-nylon collar will tighten when a dog pulls on a lead, then relaxes when the pulling stops. Also works to prevent dogs from backing out of their collars. Great for breeds with large necks and small heads like greyhounds. Each includes a hangtag.
