摘要:
A leash that allows any individual to control a pulling dog without risking injury or walking in an unsafe manner. The disclosed leash maximizes body mechanics and basic pulley/lever principles to achieve more strength. The leash comprises a cuff that preferably wraps around a users arm above the elbow. Attached to the cuff are a few feet of leash material that freely runs through an O-ring and ends in a handle. Attached to the O-ring are another few feet of leash ending with a clip that can go to a dog collar. When the dog pulls, the user pulls the handle. The resulting force goes through the O-ring, which acts as a pulley and on to the arm cuff and back of the arm, utilizing stronger shoulder and back muscles. Therefore the user is able to pull back with a lot more force than is obtainable with a typical leash.
