Answer:
White Fang learns to survive the loss of his mother and the great challenge of human punishment.
Step-by-step explanation:
When his mother gets taken, White Fang attempts to go after her by jumping into the water and swimming after the canoe. But, he ignores Grey Beaver calling him to return. Grey Beaver goes after him in a canoe and snatches him out of the water and proceeds to give him a beating for disobeying him. So, he is being punished for not listening all while having to deal with the loss of his mother.
Hope that helps.
