And the scatterbrain pup remembered her no better than she remembered him.

There is a wide gulf in intelligence between a three-month puppy and one six months old.
Yet,--perhaps because they were both excitable and mischievous and loved romping,--and because each was a novelty to the other--mother and son quickly formed a new friendship.

From the more sedate and discipline-enforcing Lad, the youngster turned eagerly to chum-ship with this flighty gold-white stranger.

And Lady, for similar reason, seemed to find ten times as much congeniality and fun in romping with Wolf as in playing with the less galvanically agile Lad.
In brief, Lady and little Wolf became inseparable companions;--this to the semi-exclusion of Lad.
The great collie did not resent this exclusion; nor did he try to regain his fast-slipping hold on Wolf's affections.

Yet, in fashion that was more pathetic than ludicrous, he sought to win back Lady's waning affection.
