For Thomas, it was the perfect demonstration of his theory about what living things provide. In place of boredom, they offer spontaneity. In place of loneliness, they offer companionship. In place of helplessness, they offer a chance to take care of another being. “[Mr. L.] began eating again, dressing himself, and getting out of his room,” Thomas reported. “The dogs needed a walk every afternoon, and he let us know he was the man for the job.” Three months later, he moved out and back into his home. Thomas is convinced the program saved his life.
