The Kurgo Auto Zip Line™ is the easiest and most convenient safety harness and restraint system for your dog. A nylon webbed line simply attaches between the two rear seatbelts or any other two fixed points, creating a tether run. This secure line allows the dog freedom to roam in the backseat of the car and allows the driver to focus on the road ahead thus reducing driver distraction. The Kurgo Tru-fit Smart Harness and Wander Leash integrate with the Zip Line allowing you to quickly transition from walking the dog to getting on the road.
