Inspired by a dog run, the Auto Zip Line allows back-and-forth plus sit-and-stand movement, but also restricts your dog’s access to the front seats allowing you to drive distraction free. This multifunctional restraint system is simple to use—the sturdy webbed strap attaches to any two fixed points, and the adjustable leash easily connects and disconnects from the zip line when getting in or out of the car, which means instant transition from vehicle restraint to walking lead.
