Just as the name suggests, hands-free leashes are designed to help you run with your dog without needing to hold on to the leash. Thereby giving your hands the freedom they need to run unhindered while keeping your dog close by you. A hands-free leash works very simply. It comes with a usually adjustable belt that goes around your waist. The waist belt is connected to a bungee leash, usually with the help of buckles or clips. The bungee leash is mostly retractable and comes with a handle or two to help control the freedom you give your dog. The leash attaches to your dog's collar or harness.
