Proudly made in the USA!
Martingale collars (often called no-slip, limited-slip collars, or simply Greyhound collars) fit comfortably on a dog’s neck and tighten gently when necessary. These collars are perfect for greyhounds, whippets, afghans, and other sighthounds whose necks are larger than their heads because it safely prevents your dog from escaping or slipping out of their collar.
The stainless steel hardware will never rust or corrode and the webbing can literally be used to tow cars. It will not break or fray, no matter how hard your dog pulls.
