Allen Parton came home from the Gulf War in 1991 unable to walk, talk, or remember his wife and children. Doctors told Sandra to leave him. A Labrador named Endal - rejected from service training - learned 200 commands from Allen's gestures and rebuilt his capacity to feel. When a car knocked Allen out in 2001, Endal put him in the recovery position, retrieved his phone, and ran to a hotel for help. Endal was best man when they remarried.
