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:
Has she had her antacid now?
Can she keep water down?
Are her gums pink or pale/white? Moist or sticky?
If you press on her belly, does she have any discomfort, distension, tenderness, or tensing?
Could she have eaten something she should not have (ie bones, toys, plants, chemicals, etc)?
Has she had any diarrhea?
Can you take a breathing rate for me (just count her breaths for 10 seconds + multiply that by 6)?
