A good source of internal conflict in this story might be the determination of Billy. Although he is not affluent or naturally skilled, he overcomes obstacles by showing "grit" and saving for two years in order to buy his dogs. He loves them dearly, and he showed it by dealing with the uncertainty and hardship. Another conflict is when Old Dan and Little Ann were out coon hunting and they come across a mountain lion. Another conflict is when Billy was going by the school in town and gets harassed by the students and made fun of.
