The Beaphar Gentle Leader® is a unique, patented design that has been scientifically developed to work with your dog's natural instincts in order to control unwanted pulling on the lead. The Beaphar Gentle Leader® provides kind and effective leadership, and makes training at home quick, simple and fun for both you and your dog. A dog's natural instinct is to pull on the lead. The Beaphar Gentle Leader® helps to counter this in three ways: 1. Gentle pressure is transferred to the back of the neck, naturally stimulating a relaxation response (the same as when a mother carries a puppy by the scruff of its neck). 2. Gentle pressure is applied around the muzzle from the nose loop, communicating your reassuring control. 3. It works like a halter rope – where the nose goes, the body will follow. The Beaphar Gentle Leader® was designed by veterinary surgeon Professor Robert Anderson, Director of the Animal Behaviour Clinic at the University of Minnesota, USA and Ruth Foster, former President of the American National Association of Dog Obedience Instructors. The Beaphar Gentle Leader® is easy-to-fit and adjust. Suitable for dogs from 8 weeks of age.
