Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you today. I do apologize that your question was not answered before. Different experts come online at various times; I just came online, read about your situation, and wanted to help.
Again I do apologize that my colleagues could not help you sooner. If you would still like assistance, can you tell me:
How long has she had these signs?
Can you take a breathing rate for me (just count her breaths for 10 seconds + multiply by 6)?
Are her gums pink or pale/white?
If you press on her belly, is it tense, sore, or hard?
Does she favor any leg or have tenderness when you press/move her back or spine?
Any history or a slip, fall, or trauma?
