I love the control this leash gives me. Not only can I give my dog freedom when it is appropriate, I can use the same leash to work on his walking directly beside me. The second handle has made all the difference in the world when it comes to being able to correct the roaming behavior without having to fumble with a bunch of extra leash material. The second handle also made it easier to maintain the consistency in the length of leash given when he needed to be right beside me. Since the second handle is permanently attached, I didn't have to worry about how close I was pulling him each time to not confuse him. All worries of that are now gone.
