what does the man in the red sweater teach buck?

Also known as the man with the club. He metes out discipline to all dogs that will be sold for sledding. Ruthless in his repeated beatings of unruly creatures such as Buck, he maintains composure and control. He does not beat out of cruelty, it seems. Rather, he looks to teach these dogs the lessons that will allow them to survive in this harsh environment. Buck never forgets the law of the club.
