Does she know "give" (present whatever's in her mouth to your hand)? How about "drop it"?
I think of Leave It - Drop It - Give to be the trifecta of corrective commands. You know you've been successful when the only one you need is Leave It.
I always used "up up" with all of the dogs to indicate that I wanted them to get on/in something, e.g., the back of the SUV (for the ones allowed to jump in on their own), the scale at the vet. I used "kennel up" and "crate" for the dogs using those particular things.
Dan also knew "back up".
