【AutoBrake System on Leash】- The basic theory is similar as is found in the car seatbelt, but designed specifically for a dog that has not yet learned not to pull. The function does not just to stop your dog, but it also has a damping device which helps to absorb the pulling and encourage your dog to slow down. Of course, you will need to choose the correct size leash for a better experience of the auto braking and shock absorbing features.
