White Fang
Jack's attempts to tame White Fang eventually succeed; both wolfdog and man develop a close and trusting bond. Alex helps Jack mine for gold and they strike it rich with the help of White Fang. One morning, Jack travels to the town to claim proper ownership to the gold when Luke notices White Fang with him. Seeking retaliation and planning to steal the gold, Smith and his men attack the cabin site. White Fang attacks Tinker, who accidentally discharges his gun, wounding Luke. White Fang subdues Smith until he's ordered by Jack to back down. Jack and Alex take Smith and his men prisoner and force them at gunpoint to haul gold ore into town.
