Likewise he learned to romp with the master, to be tumbled down and rolled over, and be the victim of innumerable rough tricks. In return he feigned anger, bristling and growling ferociously, and clipping his teeth together in snaps that had all the seeming of deadly intention. But he never forgot himself. Those snaps were always delivered on the empty air. At the end of such a romp, when blow and cuff and snap and snarl were fast and furious, they would break off suddenly and stand several feet apart, glaring at each other. And then, just as suddenly, like the sun rising on a stormy sea, they would begin to laugh. This would always culminate with the master’s arms going around White Fang’s neck and shoulders while the latter crooned and growled his love-song. But nobody else ever romped with White Fang. He did not permit it. He stood on his dignity, and when they attempted it, his warning snarl and bristling mane were anything but playful. That he allowed the master these liberties was no reason that he should be a common dog, loving here and loving there, everybody’s property for a romp and good time. He loved with single heart and refused to cheapen himself or his love. The master went out on horseback a great deal, and to accompany him was one of White Fang’s chief duties in life. In the Northland he had evidenced his fealty by toiling in the harness; but there were no sleds in the Southland, nor did dogs pack burdens on their backs. So he rendered fealty in the new way, by running with the master’s horse. The longest day never played White Fang out. His was the gait of the wolf, smooth, tireless and effortless, and at the end of fifty miles he would come in jauntily ahead of the horse. It was in connection with the riding, that White Fang achieved one other mode of expression—remarkable in that he did it but twice in all his life. The first time occurred when the master was trying to teach a spirited thoroughbred the method of opening and closing gates without the rider’s dismounting. Time and again and many times he ranged the horse up to the gate in the effort to close it and each time the horse became frightened and backed and plunged away. It grew more nervous and excited every moment. When it reared, the master put the spurs to it and made it drop its fore-legs back to earth, whereupon it would begin kicking with its hind-legs. White Fang watched the performance with increasing anxiety until he could contain himself no longer, when he sprang in front of the horse and barked savagely and warningly. Though he often tried to bark thereafter, and the master encouraged him, he succeeded only once, and then it was not in the master’s presence. A scamper across the pasture, a jackrabbit rising suddenly under the horse’s feet, a violent sheer, a stumble, a fall to earth, and a broken leg for the master, was the cause of it. White Fang sprang in a rage at the throat of the offending horse, but was checked by the master’s voice.
