Thanks hazelrunpack. Yes, she still shakes when we get her up and try to get her outside to pee. That was always her fear reaction in the past to thunderstorms etc. She obviously has no idea why this is happening and it seems to give her much anxiety. She is so stiff when we get her up she really doesn't want to move. It must be strange to feel that disoriented. I really hope we see some type of improvement in the next two days but it has only been 24 hours now since this started. They say there should be a marked improvement within 72 hours and she might show symptoms for 1-2 weeks. My brother's dog is 17 and she has had two episodes. Unfortunately, she still has a head tilt and is fairly wobbly. This seems permanent since it has been months since the last episode.
I'm glad your Grace got better after a week. Just curious how old she was at the time? Was there any known cause in her case?
