Add extensions to any leash, so that the best leash can be selected without limits! Dual Tangle-Free Dog Walking! Add 2 extensions to an EzyDog Leash and the 3 swivel points allow for 2 dogs to walk without getting tangled. Just like magic. Slip the clip through the ring for use as a Choke Collar for training or for times when a collar isn’t available. Wrap the extension around a pole and slip the clip through the ring for a Quick Tether. Reflective Strands are built into the Extensions to be seen at night.
