The Call of the Wild is a novel by American author Jack London published in 1903. The story is set in the Yukon during the 19th-century Klondike Gold Rush—a period when strong sled dogs were in high demand. The novel's central character is a dog named Buck, a domesticated dog living at a ranch in California as the story opens. Stolen from his home and sold into the brutal existence of an Alaskan sled dog, he reverts to atavistic traits. Buck is forced to adjust to, and survive, cruel treatments, fight to dominate other dogs in a harsh climate. Eventually he sheds the veneer of civilization, relying on primordial instincts through lessons he learns, to emerge as a leader in the wild.
London lived for most of a year in the Yukon and gained from that experience material for the book. The story was serialized in the Saturday Evening Post in the summer of 1903; a month later it was released in book form. The novel’s great popularity and success made a reputation for London. Much of its appeal derives from the simplicity with which London presents the themes in an almost mythical form. As early as 1908 the story was adapted to film, and it has seen several more cinematic adaptations since that time.
The story opens with Buck, a large and powerful St. Bernard-Scotch Collie, living happily in California's Santa Clara Valley as the pet of Judge Miller. He is stolen by the gardener's assistant, however, and sold to fund the latter's gambling addiction. Buck is then shipped to Seattle. Put in a crate, he is unfed and beaten by the "man in the red sweater". When released, he attacks the man but is badly beaten and taught to respect the law of the club. Buck is then sold to a pair of French-Canadian dispatchers from the Canadian government, François and Perrault, who take him with them to the Klondike region of Canada. There they train him as a sled dog. From his teammates, he quickly learns to survive cold winter nights and the pack society. A rivalry develops between Buck and the vicious, quarrelsome lead dog, Spitz. Buck eventually beats Spitz in a fight "to the death". Spitz is killed by the pack after his defeat and Buck eventually becomes the leader of the team.
