The dog started to think maybe this man shouldn't be trusted. The dog knew they shouldn't be traveling but the man insisted. It started to become angry with his master. The voices inside of it grew and were kindled by the cold like a fire is by fuel.
It roared as it's claws slashed the man's back. He flew around and charged back. It did not care anymore, the urges were too strong, the voice too vivid besides, the dog was cold and angry with him.
The beast flew at the man's neck and squeezed it's jaw shut. As he fell, the wolf-dog "obeyed the commands that arose from the deepest part of it's being" (London, 69). It now knew nothing but the warmth of blood.
