rule #2: when you think the humans aren't watching, snatch the treats. sometimes the treats can be tricky, like when there's not a lot left. but, you must always find a way to get to the bottom of that treat bag.
you might need to walk around and tilt the bag so they all come falling toward your mouth.
make sure you know how to take the bag off your head though. at this point my human caught me with my head in the treat bag and had to help me take it off, since it got stuck.
