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.
Again I do apologize that my colleagues could not aid you sooner, but can you tell me:
How long has she been showing signs?
What does her urine look like? Watery/dilute or dark? Any blood?
Does she pass small or large volumes?
Did she vomit just the once? Can she keep water down?
Are her gums pink or white/pale? Moist or sticky?
If you press on her belly, does she have any tensing, tenderness, discomfort, or pain?
Could she have eaten anything she should not have (ie bones, toys, plants, chemicals, human meds, etc)?
