I guess D: none of the above. Actually, Trixie does all of these things, but if you gave her these exact verbal commands, she would look at you like you're nuts! We can get her to do anything by snapping our fingers in a certain motion or direction. It's pretty cool actually. Funny thing is, we have no idea where she picked it up! We didn't purposely teach her to do this, I guess we were snapping at her when we were training her and she picked it up?
OK...I take that back, she does know what 'sit' is...and 'get up' if she's on me and I need to move.
