How did the other dogs feel about the new leadership?

From the text:

But it was in giving the law and making his mates live up to it, that Buck excelled. Dave and Sol-leks did not mind the change in leadership. It was none of their business. Their business was to toil, and toil mightily, in the traces. So long as that was not interfered with, they did not care what happened. Billee, the good-natured, could lead for all they cared, so long as he kept order. The rest of the team, however, had grown unruly during the last days of Spitz, and their surprise was great now that Buck proceeded to lick them into shape.

Pike, who pulled at Buck's heels, and who never put an ounce more of his weight against the breastband than he was compelled to do, was swiftly and repeatedly shaken for loafing; and ere the first day was done he was pulling more than ever before in his life. The first night in camp, Joe, the sour one, was punished soundly--a thing that Spitz had never succeeded in doing. Buck simply smothered him by virtue of superior weight, and cut him up till he ceased snapping and began to whine for mercy.

The general tone of the team picked up immediately. It recovered its old-time solidarity, and once more the dogs leaped as one dog in the traces. At the Rink Rapids two native huskies, Teek and Koona, were added; and the celerity with which Buck broke them in took away Francois's breath.
