Martingale Collars are made to prevent your dog from slipping out of its collar while being walked on a leash and can also be used as a training collar. The collar is often referred to as a humane choke collar. They feature a twin loop design that works by tightening around your dog's neck whenever it tries to pull or slip out its collar. Then, the Martingale will loosen again when your dog stops struggling against it.
Our martingale collars are measured fully extended. When measuring your dogs neck, please measure his neck near the top portion and be sure to press down through all its fur to get an accurate measurement. Most people do not press down the fur to get a correct measurement. This leads to them over measuring their dog's neck. And leads to them ordering a size that is too large.
Warning: Martingale collar is not for tie out. Never leave your dog unattended with a collar on. This product is not recommended/designed to use without leash and not for indoor use.
