The call of the wild

"Buck did not read the newspapers, or he would have known that trouble was brewing, not alone for himself, but for every tide-water dog, strong of muscle and with warm, long hair, from Puget Sound to San Diego..." The Call of the Wild is a short adventure novel by Jack London published in 1903 and set in Yukon, Canada during the 1890s Klondike Gold Rush, when strong sled dogs were in high demand. The central character of the novel is a dog named Buck.
The story opens at a ranch in the Santa Clara Valley of California when Buck is stolen from his home and sold into service as a sled dog in Alaska. He progressively reverts to a wild state in the harsh climate, where he is forced to fight to dominate other dogs. By the end, he sheds the veneer of civilization and relies on primordial instinct and learned experience to emerge as a leader in the wild.
The story was serialized in the Saturday Evening Post in the summer of 1903, it was published a month later in book form. The book's great popularity and success made a reputation for London.
