The work tells the story of Buck, a pet dog of Judge Miller’s family, who has been living in a warm valley in southern California after being civilized. He was sold to the cold, remote, gold-rich northern state of Alaska as a sled dog. The dog who should represent the civilized world as a dog is forced to return to barbarism by his master. Growing up in a greenhouse, Buck was stolen and sold to the wild as a sled dog. The cruel reality touched Buck’s instinct and consciousness of returning to nature due to the long influence of human civilization. Buck was trained by the harsh living conditions, and he grew through them. In the end, he won the first place in the sled dog pack by defeating the king Spitz. When the cruel Hal had beaten Buck black and blue and was almost dead, John Thornton’s rescue made Buck feel warm and decided to pledge his loyalty to his patron to the end. However, the death of the benefactor completely broke Buck’s attachment to human society, so Buck was determined to go to the wilderness and return to nature.
First of all, the image of the dog in the novel is in sharp contrast to the image of the human. Dogs (Buck) are brave, kind, loyal, grateful, highly adaptable, and have excellent leadership skills, while humans are mostly hypocritical and tyrants. Buck was sold to a dog dealer and moved from the comfort of Judge Miller’s home to the rigors of northern life, but he soon adapted to the rules of existence. Even if there were no foreboding in the air, he could dig a hole by a tree or a bank, and hide safely from the strong wind. Buck used the best of management to keep the dogs in order. It pulled up a thousand pounds of flour and won the bet. Humans, on the other hand, still treat dogs with ropes, cages, and sticks. To satisfy their own desires, they do not care about the fate of other creatures. Man thinks he has the right to truth, and he thinks he is the supreme master of the dog. It is just because of a series of selfish behaviors of human beings that lead to the tragic fate of the dogs, and at the same time, human beings also suffer bad consequences. Hal and his family are buried in the White River, and Buck finally returns to the wilderness.
