More than 5 million dog owners have found the secret to stress-free walks! The Gentle Leader Headcollar stops pulling, lunging, jumping, and other unwanted behaviors with immediate, gentle control. Unlike traditional collars, the Gentle Leader places pressure on the back of the neck instead of the front of the delicate throat, preventing choking and coughing. The nose loop allows you to direct your dog's head in the direction you want to go. Most dogs quickly learn to stop pulling and start paying attention to you during walks.
