Can you give her a puzzle ball or toy to keep her occupied? I use a Kong Wobbler sometimes and put their breakfast kibble in it with larger pieces of dried liver that can't come out and it keeps them occupied for hours - they have to really work to get their food and it does tire them out.
Otherwise give her a large meaty bone or a nylabone if you prefer.
It won't hurt her to miss out on exercise for a day or 2.
