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:
Did her vet send her home on any treatment?
Did they do any tests?
Did they note belly pain? Does she have that now?
Can she move her back legs at all? If you pinch a back toe, can she feel it?
Could she have eaten anything she should not have (ie bones, toys, plants, chemicals, human meds, etc)?
Are her gums pink or white/pale? Moist or sticky?
