The direct to seat belt tether from Kurgo is designed to prevent distracted driving, which spares the trouble of undoing the seat belt every time your dog gets in or out. Simply click the direct to seat belt tether into the female slot of a seat belt, and it can just live there. When your dog hops in, simply attach the opposite end to his/her harness via the included carabiner, and off you go - your dog is safely in the back seat while you are in the driver\'s seat.
