Answer:
The relationship between Buck and John Thornton symbolizes the bond between animals and humans. John is the pull that keeps Buck from going wild. When Buck lives with the judge, he lives like a king. Everything is his domain, but he is not especially close to anyone. All of the humans from there on are exploitative, ignorant, or abusive. Then Buck meets John Thornton, and it is a relationship based on love and trust.
