The story begins before the three-quarters wolf-dog hybrid is born, with two men and their sled dog team on a journey to deliver a coffin to a remote town named Fort McGurry in the higher area of the Yukon Territory, Canada. The men, Bill and Henry, are stalked by a large pack of starving wolves over the course of several days. Finally, after all of their dogs and Bill have been eaten, four more teams find Henry trying to escape from the wolves; the wolf pack scatters when they hear the large group of people coming.
The story then follows the pack, which has been robbed of its last prey. When the pack finally brings down a moose, the famine is ended; they eventually split up, and the story now follows a she-wolf and her mate, One Eye. The she-wolf gives birth to a litter of five cubs by the Mackenzie River, and all but one die from hunger. One Eye is killed by a lynx while trying to rob her den for food for the she-wolf and her cub; his mate later discovers his remains near the lynx's den. The surviving cub and the she-wolf are left to fend for themselves. Shortly afterward (possibly as revenge), the she-wolf kills all the lynx's kittens to feed her cub, prompting the lynx to track her down, and a vicious fight breaks out. The she-wolf eventually kills the lynx but suffers severe injury; the lynx carcass is devoured over a period of seven days as the she-wolf recovers from her injuries.
The cub comes across five Native Americans one day, and the she-wolf comes to his rescue. One man, Grey Beaver, recognizes the she-wolf as Kiche, his brother's wolfdog, who left during a famine. Grey Beaver's brother is dead, so he takes Kiche and her cub and christens the cub White Fang. White Fang has a harsh life in the Indian camp; the current puppy pack, seeing him as a wolf, immediately attacks him. The Indians save him, but the pups never accept him, and the leader, Lip-lip, singles him out for persecution. White Fang grows to become a savage, callous, morose, solitary, and deadly fighter, "the enemy of his kind".
It is at this time that White Fang is separated from his mother who is sold off to another Indian Camp. He realizes how hard life in the wild is when he runs away from camp and earns the respect of Gray Beaver when he saves his son Mit-Sah from a gang of bullies. When a famine occurs, he runs away into the woods and reunites with his mother Kiche, only for her to chase him away for she has a new litter of Cubs. He also encounters Lip-Lip whom he fights and kills before returning to the camp.
When White Fang is five years old, he is taken to Fort Yukon so that Grey Beaver can trade with the gold-hunters. There, he is bought with several bottles of whiskey by a dog-fighter, Beauty Smith, who gets Grey Beaver addicted to alcohol. White Fang defeats all opponents pitted against him, including several wolves and a lynx, until a bulldog called Cherokee is brought in to fight him. Cherokee has the upper hand in the fight when he grips the skin and fur of White Fang's neck and begins to throttle him. White Fang nearly suffocates but is rescued when a rich, young gold hunter, Weedon Scott, stops the fight and forcefully buys White Fang from Beauty Smith.
Scott attempts to tame White Fang, and after a long, patient effort, he succeeds. When Scott attempts to return to California alone, White Fang pursues him, and Scott decides to take the dog with him back home. In Sierra Vista, White Fang must adjust to the laws of the estate. At the end of the book, a murderous criminal, Jim Hall, tries to kill Scott's father, Judge Scott, for sentencing him to prison, not knowing that Hall was "railroaded". White Fang kills Hall and is nearly killed himself but survives. As a result, the women of Scott's estate name him "The Blessed Wolf." The story ends with White Fang relaxing in the sun with the puppies he has fathered with the sheep-dog Collie.
