Description
Martingale collars help prevent a dog from backing out of its collar. When there is tension on the leash, the martingale will reduce the size of the collar by a limited amount, preventing the collar from pulling off over the head (when the collar is properly adjusted). When the leash is slack, the collar relaxes to a looser fit as determined by the adjusted size of the collar. The Martingale Combo collar has a second D-ring which is sewn into the collar. It does not change the size of the collar
