In Part Three, the cub and its mother wander into an Indian camp, where the mother is recognized by an Indian named Gray Beaver; she answers immediately to the call of "Kiche," and the little gray cub is promptly named White Fang. In the Indian camp, the cub has to learn how to function in the presence of the Indians, and he must also learn how to protect himself against the other puppies. When his mother is taken from him, he attempts to follow her, but he is severely beaten by Gray Beaver, and thus he quickly learns another lesson — to obey the "man-god." When Gray Beaver goes to the nearest fort to sell his furs, he takes White Fang with him. There at the fort, White Fang becomes famous for his ferocious ability to kill other dogs, and he is sought after by a vicious, ugly man named, ironically, Beauty Smith, who, by using trickery and alcohol, is able to trick Gray Beaver into selling White Fang to him. White Fang is treated terribly by this cruel man; he is constantly forced into bloody fights with other dogs so that Smith can win bets. But during one fight with a bulldog, White Fang is at the point of being killed when a man named Weedon Scott, a person of distinction and authority, interferes and stops the fight. Furthermore, Scott pays off Beauty Smith and threatens to have him jailed. Scott then takes White Fang with him.
Under the protection and patience and compassion of Weedon Scott, White Fang gradually learns to appreciate a human being, and ultimately he comes to possess a love and affection for Scott.
When Weeden Scott has to return to his home in the Southland (California), he at first intends to leave White Fang behind. White Fang, however, escapes and sneaks aboard the ship. Scott, therefore, chooses to take the dog along. The novel ends by showing how White Fang learns to exist as a domesticated animal. Ultimately, White Fang wins the affection of Scott's family because of his extreme intelligence (for example, he leads some men to help his injured master) and also because of his performing an act of bravery by risking his life to save Judge Scott from being murdered.
