Abstract: An animal restraint to securely restrain an animal in a truck bed having bed side walls comprises an elongate threaded rod of a length somewhat less than the distance between the truck bed side walls, terminating in two side attachment portions for connection to the side walls. These side attachment portions each enable length adjustment so that the system can be adjusted to fit in various widths of truck beds. A restraint centering device serves to secure a swivel member at some point along the length of the threaded rod. A restraint lead is connected, as by a clamp, to this centering device swivel member, and terminates in a snap or fastener attachable to an animal collar. Therefore, an animal attached to the restraint lead snap is prevented from reaching either truck bed side wall.
