White Fang, published in 1906, is another of Jack London's celebrated works and serves as a companion piece to The Call of the Wild. While The Call of the Wild focuses on a domesticated dog's return to the wild, White Fang tells the story of a wild wolfdog's journey towards domestication.

Set in the Yukon Territory during the Klondike Gold Rush, the novel follows White Fang, a wolfdog born in the wild. Unlike Buck, who starts as a domesticated pet, White Fang begins life in the wilderness and experiences the brutal realities of the natural world. As he grows, White Fang encounters various humans, some kind and some cruel, and undergoes a gradual transformation from a fierce, wild animal into a more domesticated creature.

The novel explores themes of survival, the impact of environment and experiences on personality, and the potential for redemption and change. London's portrayal of White Fang's evolution reflects his interest in the duality of nature-both wild and civilized-and the capacity for growth and adaptation in the face of changing circumstances.
