Kazan, the Wolf Dog - James Oliver Curwood - Bog

Yet every drop of the wild blood in his splendid body was racing in a ferment of excitement that Kazan had never before experienced; every nerve and fiber of his wonderful muscles was tense as steel wire. Quarter-strain wolf, three-quarters "husky," he had lived the four years of his life in the wilderness. He had felt the pangs of starvation. He knew what it meant to freeze. He had listened to the wailing winds of the long Arctic night over the barrens. He had heard the thunder of the torrent and the cataract, and had cowered under the mighty crash of the storm. His throat and sides were scarred by battle, and his eyes were red with the blister of the snows.
