Police say the man awoke around midnight to the sound of someone trying to make off with the vehicle from their northwest-area home.
He confronted the thief in an alley and was initially pinned against a fence before he was dragged.
The homeowner was taken to hospital with what were feared to be life-threatening injuries, but his condition has been upgraded to stable.
The pickup was found abandoned a few blocks away and police say they're investigating a possible link between it and another stolen truck discovered nearby.
A suspect is still being sought.
