I realized Bella knows a few words really well -
Leave it - first thing we taught her as we lived in NYC at the time and there's all manner of nastiness for a dog to get into
OK - opposite of "leave it", as in "ok, you can have that treat". A friend of ours gave her part of a steak one time and she waited until she heard "ok" to take it!
Off - to get her to remove herself from furniture
Out - out of the kitchen. She has two spots to watch all of the action
Bed - to go to her bed when we sit down for dinner
Walk, car ride, potty, cookie - these, of course, result in bouncing, play bows and abbreviated zoomies
