Abstract: An apparatus primarily for use with dogs which prevents the animal from jumping or being thrown from the open bed of a pickup truck. The apparatus uses a main cable removably attached at one end to a hinge mounted to the front panel of the truck bed. The opposite end of the main cable is removably attached to a second hinge mounted to the truck bed floor adjacent the tailgate. Attached generally centrally on the main cable are two spaced cable clamps. The position of the two cable clamps is adjustable on the main cable. A short leash is removably and slidably attached to the main cable between the two cable clamps. The opposite end of the leash removably attaches to the collar of an animal. The frontward to rearward movement of the animal in the truck bed may be controlled by locating the cable clamps on the main cable to prohibit the leash from sliding excessively close to one end of the other of the truck bed.
