Non-stop dogwear Bungee leash double is a bungee with an intergrated Y leash. The bungee is developed for professional racing, but also works for an everyday active dogowner that wants to have two dogs pulling at the same time. Bungee leash double reduces strain on both you and the dog. The part with the Y leash is static, while the rest of the bungee is elastic. The bungee comes with twist-lock carabiners that lock automatically. The carabiner rotates so the bungee will not twist.
