Features: ensure both you and your doggy thoroughly enjoy your walk! And we've achieved This by giving your pup room to explore and giving you maximum control through our leash unique "Brake & Lock" System. We've turned up the control with an ergonomic anti-slip handle, so the retracting Leash will never get away from you even if your beefy pooch suddenly pulls or runs. Special note: make sure that all parts of the leash and your dog's collar are in good condition. If any part of the leash or your dog's collar is damaged, frayed or broken, please do not use The leash. Never try to open the plastic casing, disassemble any other parts, The spring inside may cause unexpected injuries. Don't allow too small children to use The leash. For safety reasons, keeps your dog at your side before any possible dangerous situation emerges.
