Thy Dear Lady's Affection Waxes then Wanes

I think Lady, our one year old puppy, is having an identity crisis.   Is she a lover of foxes?

Or a lover of the giraffe?

Or a lover of ducks?

Or, is she simply a fickle creature, prone to nuzzling whatever nearby creature still harbors an operational squeaker within?

As her affection for the duck wanes the same as her affection for the giraffe and the fox withered with time, what will she nuzzle, chew, and frolic next?  

Your guess is as good as mine.  Perhaps, I'll go to Petsmart and find out.
