Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with 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:
Has she been drinking more since exposed to the grapes?
Does she pass large volumes of watery urine?
What does her stool look like? Watery, formed at all?
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 else she should not have (ie bones
, toys, rocks, plants, chemicals, etc)?
