TishaMoon, why don't you try "Down" for a while instead? Training should be fun for both of you.
I have been trying to get Thor to Roll Over for forever and he seemed reeeeeeeeally close last week. Yesterday, I found myself trying the command Roll Over, You Dumb Dog! I think I'm going to work on Watch Me for a while.
I do have hope because it also took forever for Thor to get Shake, and now that's one of his favorites.
Oh, also: if she's jumping around a lot, try doing a training session after she's had a long walk or training session. Hopefully she'll be less, "Omigod Give Me The Treat I Want The Treat It's A Treat!!!!!!"
