Reflective Elastic Dog Car Seat Belt Tether, Adjustable

This tether links your dog's harness to a seat belt buckle in the car, so your dog stays on the seat instead of wandering around the vehicle. One end has a metal tongue shaped to click into a seat belt buckle, and the other has a swivel clip with a screw-lock gate that you attach to a harness. Reflective stripes run along the polyester webbing, and the zinc alloy hardware looks sturdy and compact.

The strap has an elastic section that stretches, and it adjusts in length. At its shortest it measures about 27.6 inches (70 cm), and at its longest it stretches to about 49.2 inches (125 cm). A shorter setting keeps a small dog close to the seat, while a longer one gives a bigger dog more room to sit or lie down. It weighs about 6.5 oz (185 g), so it is light enough to keep in the glove box.

Attach it to a harness, not to a collar, so that any pull is spread across your dog's chest rather than the neck. Adjust the length before every trip so your dog can sit or lie down but not reach the front seat or the window. Check the strap for fraying and the clip for wear regularly. It comes in black or dark gray. Wipe the webbing with a damp cloth.
