Start here: What might a pet need to learn in a cold wilderness?
Jack London published The Call of the Wild in 1903. Its main character is Buck, a large dog who lives comfortably in California. During the Klondike Gold Rush, strong dogs are valuable because they can pull sleds carrying people and supplies.
Buck is stolen and sold. He is taken north, where his easy life is replaced by snow, hard work and danger. He has to learn how to pull a sled, find food and protect himself. He watches other dogs and adapts to the harsh conditions.
Buck becomes stronger and eventually leads a sled team. However, not all his owners understand the wilderness. Some treat the dogs badly and push them beyond their strength. John Thornton saves Buck from a cruel owner and cares for him.
Buck develops a deep loyalty to Thornton. He protects him and performs remarkable feats of strength. At the same time, the sounds and smells of the forest attract him. He explores farther from camp and feels drawn towards a life beyond people.
After Thornton is killed, Buck’s last close connection to human life is broken. He joins a wolf pack and becomes part of the wilderness. He does not turn into a wolf: he remains a dog whose way of life has changed.
The story explores survival, loyalty and belonging. London imagines Buck’s thoughts and instincts, so this is fiction rather than scientific evidence about dogs. The title suggests the pull Buck feels towards the wild.
