The Auto-brake Dog Leash is designed for a safer and more controlled walking experience. Available in two lengths, 3 meters and 5 meters, this leash is perfect for small, medium, and large dogs. With its unique auto-brake feature, it automatically stops pulling to prevent sudden jerks, ensuring both you and your pet stay comfortable and safe. The one-button lock provides quick control, while the U-shaped outlet prevents tangling, allowing for smooth operation.
