Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
What is she bringing up in her vomit?
Is she eating? Can she keep water down?
Are her gums nice and pink (not white/pale)? Moist or sticky?
If you press on her belly, does she have any tensing, tenderness, discomfort, or pain?
Could she have eaten anything she should not have (ie bones, string, hair bands, toys, plants, chemicals, human meds, etc)?
Did you switch her food before or after the vomiting?
If before, was it a gradual wean or quick switch?
Has she had any diarrhea
