What are the ambitions of Dave and Sol-lek? (Chapter 2)

Dave is one of Buck's first companions, he is one of the most knowledgeable dogs on the team. Mostly aloof, new life springs into him the moment he is placed in a harness. Not only does he help teach Buck the procedures, he also embodies pride in his work.

Sol-leks is another member of the team. Like Dave, he is aloof until attached to a sled. At first only wary of being approached on his blind-side, poor treatment makes Sol-Leks more and more unfriendly.
