Comfort Check training collar provides the same control as a regular chain collar and decreases your pet's risk of injury during training. The unique combination of nylon and chain reduces hair pulling, skin pinching and the chain noise that regular choke and chain martingale collars can cause. Warning This collar is to be used when training with a leash. It is NOT recommended to be left on unattended dogs. When securing your pet outdoors, do not use with a tie out. Regularly check the tightness of your pet's collar to prevent injury. How to find your dog's neck size Measure the circumference of your dog's neck using a cloth measuring tape and add 2 3.
