Hop into any car and go. The Deluxe Car Safety Tether lets you bring your dog with you in multiple vehicles with ease. The Deluxe Car Safety Tether is the same tether included with our Deluxe Car Safety Harness. Since the tether generally stays in the vehicle, purchasing an extra tether is the perfect way to make a second vehicle “harness ready.” This tether is compatible with all sizes of Solvit’s Deluxe Car Harnesses. Constructed from strength-rated materials and tested to 2000 lbs, the tether is adjustable in length and works in any vehicle.
