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:
What signs are you seeing?
Since she was gagging before, any more retching, gagging, lip licking, drooling, vomiting, or diarrhea since?
Any breathing difficulties?
Are her gums pink or white/pale? Moist or sticky?
If you press on her belly, any tensing, tenderness, discomfort, or pain?
