What are White Fangs abilities described in Chapter 15?

From the text:

He was too quick for them, too formidable, too wise. He avoided tight places and always backed out of it when they bade fair to surround him. While, as for getting him off his feet, there was no dog among them capable of doing the trick. His feet clung to the earth with the same tenacity that he clung to life. For that matter, life and footing were synonymous in this unending warfare with the pack, and none knew it better than White Fang.

He became an adept at fighting. He economised. He never wasted his strength, never tussled. He was in too quickly for that, and, if he missed, was out again too quickly.
