Arriving at Sierra Vista, Scott embraces his mother, which causes White Fang to become a "snarling, raging demon." When White Fang is reprimanded by his master, he is finally satisfied that the woman is not going to hurt Scott. This, however, is only the beginning of many experiences which White Fang will have to undergo until he becomes domesticated. Fortunately, White Fang has sufficient intelligence to totally obey Weedon Scott's commands. When they arrive at the Scott estate, for example, they are greeted by a large sheepdog named Collie, who tries to attack White Fang immediately upon seeing him. White Fang instinctively knows, though, that this is a female of the species, so he turns his shoulder and shunts her attacks. The sheepdog, out of an ancient instinct, knows that this wolf is a natural enemy to her position as a protective sheepdog. Thus, Collie, the sheepdog, is introduced to us as the antagonist of White Fang, and her attack upon him will continue for some time. In fact, she will be the main bane of White Fang's existence for some time. This is ironic because the novel will end with White Fang going off into the forest with the sheepdog in order to mate with her and thus begin a new breed of dog.
Upon their arrival at the house, a dog named Dick runs to greet Weedon Scott, and White Fang instinctively feels that his master is being attacked, and again he is prepared to kill. And he would have done so, had not Collie hit White Fang from the side and broke the line of his attack, which allows Weedon Scott time enough to stop the fight. Weedon knows that White Fang could have easily killed Dick.
After his first introduction to the estate, White Fang has a series of things which he has to learn. For example, the dog Dick would like to be friends with White Fang, but for too long in his life, White Fang has been adverse to friendships of any kind. Compared to the things that White Fang has to learn at Sierra Vista, life in the Northland was a very simple affair. For example, in the Northland, all that White Fang had to learn was that Mit-sah and Kloo-kooch belonged to Gray Beaver. However, in Sierra Vista, relationships are infinitely more complicated. In addition to all of the various members of Weedon Scotts family — mother, father, wife, two sisters, and two children — there are numerous servants and workers. Furthermore, White Fang has always disliked children, but now he has to learn to like Scott's children, even though they pull his fur and hit him.
