What name do the Yee-hats use for the dog leading the pack?

The name the Yee-hats use for the dog leading the pack is "Ghost Dog." This term reflects their perception of Buck, who has transformed from a domesticated pet into a powerful leader of the wild. The Yee-hats view Buck as a supernatural or mythical figure due to his strength, intelligence, and dominance in the wilderness. This connection to a "ghost" emphasizes not only the fear and reverence they have for him but also signifies Buck's evolution and his merging with the wild instincts that define him.

The other options, while they may evoke similar imagery, do not accurately represent the name the Yee-hats specifically use for him in the context of the story. This distinction is important as it highlights Buck's status and the impact he has on both his environment and the other characters within the narrative.
