Oh, lots of words. A favourite training trick when we are at the nursing home is a random ordering of SIT, DOWN, STAND. I'll give a bunch but then I will double one up and see if he is really paying attention and really knows what I'm asking.
Sit, Stand, Sit, Down, Stand, Stand. Obviously on the double Stand he should not move and usually he does not, but his whole body will give a little quiver as he anticipates a change.
