Good background. I think it seems to happen a little quick. Seeing stealing clothes, morning in a merchant caravan, that afternoon conflict with mom, later that day total breakdown. Quite a dynamic change from paying for her school to fighting, maiming, sacrificing her without caring. That is one bad day!
The plot thoughts were great and went wonderfully with the well built character. Unless there is a lot of info on the wolf, just a small paragraph on it would be fine. After all, it was with her since a puppy so his progression would go along much with hers background wise.
