Answer:
Duke was an extra-ordinary dog with special qualities, when chuck came from the hospital, Duke jumped on him and he knew instantly that he was never to jump on him again. From that movement he took up a post beside master’s bed around the clock. Duke encouraged his master to get up by poking his nose under Chuck’s elbow and lifting it up. He also nudged, needled and snorted. Finally chuck and duke began walking together with Duke pulling at the leash and holding taught so that Chuck could be supported and he could take one step forward. What began as one step at a time culminated in Chuck walking by himself.
