I´ve read until chapter 4. We can all agree now that Buck is the main character and the protagonist in the story. Buck has faced so many challenges that have helped him adapt to his new though life. One of this challenges is a dog named Spitz. Spitz seems to be the villain and trouble-maker in Buck's life. Before Buck became part of his new life with his dog and human companions, Spitz has always been the terrifying leader everyone is afraid of. Through the chapter, Spitz seems to notice how fast Buck is adapting to his new life and this seems to intimidate him. Since the beginning, Spitz has been bothering Buck and provoking him, but Buck ignores and avoids trouble with him. As time passes, Buck gets kind of tired of and annoyed by Spitz, and he starts having some fights with him. Buck starts to visualize himself as the new leader and his willing to achieve it. After some fights against Spitz, Buck and his dog companions start realizing that Spitz isn't as scary and intimidating as they thought. And this causes them all to join Buck and rebel against Spitz. In one of these fights, both, Spitz and Buck get seriously injured and at the end, Spitz is no longer an obstacle in Buck's life.
