This smooth-operating control system is especially useful for managing unexpected situations, such as approaching traffic, other dogs, or sudden distractions. The responsive brake ensures that the Pet Retractable Leash can stop instantly, helping you guide your pet safely and calmly. When you want to let your pet explore again, simply release the button and the leash extends smoothly without jerking.
