Abstract: To prevent an animal such as a dog from falling or jumping out of a pickup truck, first, second and third cables, each having a connected end and a free end have their connected ends joined together at a common connection point and their free ends terminated with a clip or snap fastener. The first and second cables are equal in length and are approximately one-half the width of the bed of the pickup truck. The length of the third cable is no greater than the length of the first or second cable. The free ends of the first and second cables are clipped to suitable points on the perimeter of the truck bed, and the free end of the third cable is clipped to the collar of the animal.
