The story Beth Gellert makes me so sad.
A man wanted to go hunting with his favorite dog but would not come when called.
When he came back he found blood everywhere and thought it was his dog that ate his son. In turn it was a wolf that came and tried to kill the boy but the dog stopped him. I would want to change the story in so that he never left his dog and went to him and saw he was fighting off the wolf and so the man never ended up killing his loyal dog.
