For his birthday we took him to the dog park to play with some friends. He and one of the beagles had a really good time rolling around in the dirt, as always.
Later that night he had his own little peanut butter "chocolate" birthday pie, complete with a candle (which he of course tried to eat while lit).
We fed him all night (since that's his favorite thing to do) and sure enough he threw up the next day. Ah well, he enjoyed himself while he stuffed his face :) That's what birthdays are all about, right? You only turn one once, live it up!
