What breed is she?
I'd try the vitamins to give her a boost. Not sure what happened there with her.
Hopefully there won't be any more problems. Keep us posted.
I'm glad to hear she's doing better.
What do you feed, including treats?
It wouldn't hurt to give her 1/4 tablet B-Complex and 400IU Vitamin E daily for a week to help give her a boost.
Do check for lice/mites, that her crop is emptying overnight and if you have photos of her and her poop...
