Wow, I don't know how I could deal with all of that either. Poor sweetie.
Probably not what you want to hear but maybe this is a good time to spay her. Then she will only need to be confined once...otherwise it is going to be 1-2 more weeks in a couple months. This way you could get it over with and it sounds like her leg is about healed.
I hate anesthesia though and am so nervous when Ellie goes under.
Oh and if she was in pain, the shaking should be normal. I'm not sure that it is normal for light sedation to cause that though. Maybe they should be using something else?
