A very sad short story

Once there was a prince, called Morgan, who lived in a big house in green valley. He had a baby son and a dog called Gelert. One day the prince left the house to go hunting, leaving the dog to take care of the baby. After some time, two hungry wolves came out of a dark jungle and ran towards the house.Gelert saw them and hide the baby under a bed. Then he bravely ran outside and started to fight the wolves. He killed them, but he has badly hurt himself. After that he was so tired that he fell asleep. After some time the prince returned and saw the dog coverd in blood. He saw his little son's bed was empty and thought Gelert had killed him. So he took his knife and killed the dog. Then he heard the baby cry and found him under the bed. Through the window he saw the two dead wolves. When he understood what had happened, he started crying.
