Martingale Collar | Dog Collars
Adjustable Martingale collars. These nylon collars are special made for use when walking and training greyhounds and other dog breeds with narrow heads. They have an extra loop that gently tightens the collar if the animal pulls, so that the collar will not slip over their head. Greyhound Martingale collars are also great for Whippets, Salukis, and similar breeds.
