What's a martingale collar you ask? Well, it was designed for dogs with thin necks, or necks as wide as the head. When you pull on the leash your dog's martingale will slightly tighten, the collar will stay put, and your dog will stay safely on its leash. This limited slip collar is perfect for dog training.
