How did Buck's eating habit change How does this occur Call of the wild?

In "The Call of the Wild," Buck's eating habits transform from a domesticated dog's reliance on regular meals provided by humans to a more primal and instinctual approach to foraging and hunting. As he adapts to the harsh conditions of the Yukon wilderness, he learns to hunt for himself and scavenge, relying on his instincts and physical abilities to survive. This evolution is driven by the necessity of survival in a brutal environment, marking his transition from a pampered pet to a fierce, self-sufficient creature. Ultimately, Buck's change in eating habits symbolizes his broader transformation into a wild animal, reconnecting with his ancestral roots.
