Oh man, just when I thought you were all set.

Is she generally a calm dog at the vet? I know some dogs can be still for x rays and not need anesthesia -- in which case, that would be a good next step. Even if she just needs sedation, that would be helpful. Get more info as to the issue. But if they have to anesthetize her, then you may want them to go straight to surgery (if they can), while she is still under.
