How long has she been vomiting?
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, tenderness, or tensing?
Could she have eaten something she should not have (ie bones, toys, rocks, plants, chemicals, etc)?
Has she had any diarrhea?
