All of these characters are round in nature. They have good and bad qualities. Additionally, Buck is the most dynamic of all the characters in Call of the Wild. He goes through the most dramatic changes. Initially a rather domesticated dog, his experience of being thrust into the wild of the Yukon, summon within him his truer, more primitive nature. This transformation gets the reader to contemplate the effects that society has on those who live in a controlled setting.
