Buck's change

When Jack London wrote The Call of the Wild, he chose a novel subject: dogs. It is not the biological dog in Fabre's scientific stories, nor the imaginary dog in myths or fairy tales, nor even the dog who plays a small role in human society. It is the dog who plays the lead role in the book and shocks readers' hearts with its life, character, taste and deeds in the ice and snow. The book features the main character Buck and his many canine companions, including his "enemies". He learns from experience. His long-gone instincts revived. Dimly he remembered the youth of his race; the ancient skill recorded in heredity by his ancestors became his skill. At the same time, his primitive wildness, his attachment to the wild life also revived. He even sat in the wilderness and gave a long howl to the moon, especially at night when he heard the wolf howl. Finally, after his beloved master was killed by the Indians, he returned to the jungle and became a group of wolves, completing his complete metamorphosis from civilization to barbarism. Ironically, it was civilized people who caused his degeneration.
