3-in-1 Dog Car Seat Belt Tether and Leash, Adjustable, Blue

This tether does three jobs. In the car, it either hooks onto the headrest or plugs into the seat belt buckle, so your dog's harness is attached to the seat instead of free in the cabin. Out of the car, the vehicle fittings can be removed and the strap used as a short leash.

The strap is high-density nylon with an elastic section that gives a little with movement, and reflective strips make it easier to see at night. A buckle in the middle lets you adjust the length from about 19.7 in (50 cm) at its shortest to about 26.3 in (67 cm) at its longest. A swivel clip turns through 360 degrees so the tether does not tangle, and the clip can be attached in a few seconds.

The headrest fittings detach, which matters if your dog likes to chew them. Use it with a harness rather than a collar, and clip it where your dog can sit or lie down but cannot reach the front seats.

The tether does not train your dog. Some dogs will tug, pull or chew on any strap, so check the nylon often for fraying. The brand name is printed on the strap near the buckle. Wipe the nylon with a damp cloth and let it air-dry; keep metal parts away from water for long periods.
