Read the two excerpts from the call of the wild describing the wolf
The wolf whirled about,pivoting on his hind legs after the fashion of joe and all concerned husky dogs , snarling and bristling, clipping his feathers together in a continuous and rapid succession of snaps
***
For the better part of an hour of the wild brother ran by his side , whining softly

How has the wolf changed?
He has become anxious about his pack
He has become friendlier toward buck
He has become timid because of the sounds
He has become stronger in his demeanor
