It is four years old and weighs about 23 kilos. His master Charles Hooper, nicknamed Chuck, works as a zone manager for a chemical company. His master's wife, Marcy, does not like Duke very much because she prefers to have a small dog, like a Pomeranian. One evening, coming back home, Chuck has an accident. He is taken to hospital where he remains for about two months. One side of his body being completely paralysed, he is sent home in a wheelchair. Duke, the dog, begins to feel that his master has difficulty in walking. Like a clever physiotherapist, he begins to exercise his master. The way he does it has been described in the story in great detail. The master is able to move a few steps on his own and resumes his duty in his office. Impressed by his great willpower and doggedness, the company promotes him to a higher rank. But unfortunately, the dog who enables his master to live a respectable life once again, gets badly wounded in an accident. Marcy immediately takes the dog to hospital but the poor dog dies the next day.
