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 wee one’s situation, and wanted to help.
If you would still like assistance, can you tell me:
Has she managed to keep any water down at all?
What did her vomit look like?
Are her gums pink or pale/white? Moist or sticky?
If you press on her belly, does she have any discomfort, tenderness, or tensing?
Could she have eaten something she should not have (ie bones, toys, rocks, plants, chemicals, etc)?
Has she had any diarrhea?
