Skipworth blue Derp martingale collar available in a 1 1/2" (13 to 16" neck) or 2" width fits (14 to 17" neck). Heavy cotton lining over the webbing. All collars are sewn on an industrial sewing machine.

PLEASE NOTE: Martingale collars do NOT have a buckle to open to put them on the dog. The collar size stated must fit over the dog's head to get it on. Collars are made to order, so if you need a longer collar add a note with your order of a size that will fit over the dog's head. Sighthounds only need neck size since their head is smaller than their neck.

What is a martingale collar? A martingale collar is made in two parts and one part tightens when you pull on the leash. The collar is made so the dog can not slip the collar off over it's head when on a leash. Instead of trying to explain I have added two photos showing a leash being pulled in one and how it looks normally in the other. Dog tags should not be attached to the d-ring but to one of the side slides. These collars are made for dogs that have a larger neck than their head. It slips on over the head. If your dog's head is larger around than their neck please measure their head to make sure the collar size will fit over it's head.
