Abstract: A portable vehicle mounted stanchion comprising a main stanchion frame to which a vertical adjustment arm is pivotably connected. The vertical adjustment arm may also be pivoted through different adjustment holes in the main stanchion frame to accommodate different animals. Two mounting brackets are bolted to the rear bumper of a vehicle, generally a pickup truck, where said mounting brackets contain vertical adjustment holes through which bolts and quick detach pins join to the stanchion frame through pivot holes. Release of the quick detach pins allows the main stanchion frame to pivot about the bolts and rest horizontally on the bed of the pickup truck.
