Wonder Walker Swivel Leash
The key point for this leash is the brass swivel which allows dogs to walk tangle free. You may adjust the length of each leash, making walking dogs of different heights easier. The swivel keeps the leashes from tangling as you walk along. You won't need to keep switching leashes from hand to hand. With snaps on the ends of both leashes, if you only want to walk one dog, the second leash may easily be removed.
