This is Nico's "feed me" face. It typically works.
I love the white stripe up Nico's nose.
When I get home from work Nico greets me with an incredible amount of enthusiasm. I have a hard time getting through our front entryway because he is plastered against my legs squirming. Once the initial greeting is over he typically grabs a toy and repeatedly presses it against me in an effort to get me to play with him. I do my best to ignore him until he has calmed down a bit because rewarding the excited energy reinforces not so polite greetings with other people, some of whom aren't appreciative of being leaned against or tripped by an excited squirming puppy.
