There were four characters in the story; the man as the protagonist, the severe winter as the antagonist and the old-timer and the dog as the minor characters. First of all, the man was the one who drove the story along with his suffering in the snow. He was first described as a person who lacked of imagination and only trusted himself. With his behaviors, like making the dog walked in front of him in order to escape from danger, we could tell that he was a proud person who only trusted himself and thought he was superior to the dog. However, if he trusted the dog’s natural instinct and stayed at the house, he wouldn’t die in the snow. The old-timer also has warned him about the harsh weather but the man wouldn’t listen to him. The man could be seen as a dynamic character because he had changed into an exhausted and frustrated person before his death, which was different from his initial attitude. The antagonist, which was the severe winter in Yukon, was always blocking the man from what he was going to do. For example, while the man was trying to build the fire, his fingers became numb and the snow fell from the branches and put out it; when he finished his lunch and started his journey, he was trapped into the water and caused him to stay for a while in order to dry his footgears. The harsh weather was a factor that molded the man to a dynamic character------ he had to modify himself in order to fit the nature. The man was also considered as a round character. He was the only character that the author spent the most time to describe. From the appearance to the habit, the author tried to represent the man as real as possible.
