What are the steps buck takes to return to the wild gradually?

In Jack London's "The Call of the Wild," Buck gradually returns to the wild by first adapting to the harsh conditions of the Yukon, learning survival skills from his experiences with other dogs and humans. He becomes more instinctual, responding to the call of the wild as he grows stronger and more independent. Eventually, he joins a wolf pack, fully embracing his primal instincts and leaving behind his domesticated past. This transformation highlights Buck's journey from a pampered pet to a fierce, self-reliant creature of the wilderness.
