[eeyore1031]

My Eeyore(1 yr old - 4lbs ) has been having diarrhea for the past few days. Her stool is not hard. Very runny. When she poop's - it's only just a little squirt after another squirt. She will have up to 6 piles of poop at a time. I took a sample to her vet today to have it tested and it was negative for any paracites. I am giving her Kaopectate (Peppermint flavor) as needed, but not doing any good... I have not changed her diet or doing anything different. She has been eating fine up until tonight. I can't get her to eat NOTHING!!! Can someone please tell me what else to try to get this diarrhea stopped. My vet told me to change her food, but I don't see that changing her food would make her stop having diarrhea. She has been on the same food from day 1.
I haven't made any changes of any kind. She just started having diarrhea a few days ago and I don't know what to do to stop it. Please Help
