Thank you for the information Elise. My vet prescript Metoclopramide which is an anti-nausea medication yesterday, I talked to my vet to have the anti-nausea, but didn't know the ondansetron works well. I will try Metoclopramide fist to see how it works then ask for the ondansetron. I am also getting the enzyme for her to try. Mao has not vomited since she got the fluid at the vet two days ago, she is still skinny, not gained any weight; she went poop right after eating, and lot of stool, I have been searching online trying to find out what's the problem, and I am wondering if it's the food allergy. I am going to get the Nature's Variety Venison for her, and to see if it can solve the problem, also the yellow stool.
