Improve and reinforce your dogs leash manners every time you take them out for a walk. When your dog pulls, the PetSafe Gentle Leader Headcollar moves their head and body back toward you refocusing their attention away from other dogs, squirrels, strangers and other distractions. Your dog will learn to let you lead the walks and stop the pulling, lunging and jumping they may be tempted to do wearing a traditional collar. The Gentle Leader places pressure on the back of the neck instead of the front of the delicate throat, preventing choking and coughing. Nose loop lets you redirect your dogs head. Includes detailed instructions and a training DVD. Colors:Black, Blue, Green, Purple, Raspberry, Red, Silver, White.
