Whatever the human is eating, the Pomeranian wants it. He stalks his prey--the fabled watermelon chunk. He studiously avoids eye contact, for he must give the appearance of disinterest if he is to close the distance without arousing suspicion. It's clearly working.
Note the Dr. Seuss quote on the wall. It reads:
Today you are You,
that is truer than true.
There is no one alive
who is Youer than You.
Be You, Pomeranian. Be the hunter that is You.
