It has been found that weight on each foot tends to diminish the tendency to wander. The present invention employs a chain of sturdy links, a portion of each end of the chain being inserted into a length of rubber tubing and a hook welded to a link on each end of the chain at one end of the tubing to engage and hold a link at the other end of the tubing to form a loop about a foreleg. The tubing not only serves to prevent chafing of the forelegs by the chain but by its inherent resistance to bending provides a biasing force to improve the securing of the engaged link of the chain with the hook.
