The Gentle Leader Head Collar is often referred to as 'The 10 minute attitude adjuster'. This is the recommended method of training your dog to walk without pulling or jumping up, in conjunction with positive reinforcement. Light pressure is exerted on the muzzle and the back of the neck, imitating the action of a mother dog on her puppies, and signals to the dog that you are in control. The head collar still allows your dog to open his mouth fully for drinking, eating, panting and barking.
