I wanted to wait a bit before writing a review, so I could get a good idea of how well this leash works. I'm pleased to say that this is one of the best leashes I've ever used! I'm currently loose leash training a 6 month lab mix who has never been trained to walk on a leash, or even wear a collar/harness. Paired with her starter harness, this leash has been incredibly effective to gently, but firmly redirect her to walk along side me, and has just the right amount of tension. It also gives her enough slack to let her explore without having the leash pulled taunt constantly. It is comfortable to hold, and after a while of successfully walking her beside me I forget it's on my wrist. I will definitely buy this leash again, if this one ever wears out!
