ok I need Ideas from your guys!

I don't really have any ideas. But since you came up with the jumping idea maybe gate off a spare room for her?

if she is crate trained - get or build a 'base for it... or even just build a 'cube' and put a mutt mat on it for her. It can be her 'place' -- teach her to go there when you say place and very soon she will figure out that it's all hers (and the other dog can't get to her)... I am now working 'place' with Cowboy - if you want some tips pm or email me.

BWT, 'place' is a crate without sides.

sorry I didn't see this before. I think I have seen sort of fabric covored ex- pens that would do the job. I'll look for a picture.
edit:
maybe you could make something similar to this
