In what way does Buck's view of humans change throughout the story?

Buck's view of humans evolves significantly throughout "The Call of the Wild." Initially, Buck sees humans in a more transactional way, as beings who hold a certain power over him. However, as he experiences various relationships with different humans, particularly John Thornton, his perspective shifts.

By the end of the story, Buck comes to view certain humans, especially Thornton, as partners and companions rather than just figures of authority or tools for survival. This evolution reflects Buck's journey towards understanding loyalty and connection, contrasting with his earlier views shaped by the harshness of a survivalist lifestyle in the wilderness. His bond with Thornton is characterized by mutual trust and respect, showcasing a deeper relationship that is more than mere utility or fear. Thus, Buck's transformation emphasizes the potential for meaningful relationships between humans and animals, highlighting the themes of companionship and loyalty.
