my 30# datsun has been vomitting about 6 x's a day.Even when she hasn't ate. She has wet and cold nose. she seems slower but not much, she drinks plenty of water. the vomit has a consistance of small bile color with some previous food in it. she is still active but loss about 15% activity. Is this an emergency or is it OK to wait a few days to see how she make out? No Diarreah.
