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:
Do you mean she is shaking like a head tremor or as if her ears/mouth are irritating her?
Are the eyes flickering back and forth quickly?
Any gagging, retching, lip licking, drooling or vomiting?
Is she drinking?
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 she should not have (ie bones, toys, rocks, plants, chemicals, etc)?
