Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.
Can she keep water down?
Any blood in her vomit or diarrhea?
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, toys, plants, chemicals, human meds, etc)?
