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.
If you do still need assistance, can you tell me:
Any chance she has been in contact with some toxic (ie plants, chemicals, human medications, etc)?
Can you take a breathing ratefor me (just count her breaths for 10 seconds + multiply by 6)?
Are her gums pink or pale/white?
Does she have a head tilt? Tremors?
Any circling in a particular direction?
Any discomfort or tensing in her belly if you press there?
