The Petbobi Dog Tie Out Cable and Stake is a heavy duty 20 ft cable with a PVC coating that protects against rust and corrosion. It is designed for use with small-medium sized dogs and cats up to 35 lbs. The spring-attached dog chain is equipped with a shock absorber to protect against neck injury from chasing animals or playing. The smooth rotation buckle reduces tangles in the cord and prevents the dog from becoming entangled in the cable.
