With its innovative Short-Stop Braking System, it creates a high level of safety and comfort during walks. Flexi retractable leashes never slacken as they are always subject to slight tension. With the help of the integrated braking system, you are always able to guide and command your dog. By pushing the brake button with your thumb and a slight pull on the leash you give your dog short orders or leash him back to you. An additional permanent stop function allows you to fix the flexi leash at a certain length.
