How much does she weigh?
What color are the gums?
From your history - it certainly sounds like there may be a a colitis.
This can be from many different causes including eating something abnormal and even certain types of infections including intestinal parasites, giardia, and coccidia.Here is a great link that talks about colitis. http://www.VeterinaryPartner.com/Content.plx?P=A&S=0&C=0&A=677 If you would like to try conservative management at home, you can try to offer a bland diet. A common bland diet is boiled chicken and rice (2/3 rice and 1/3 chicken). I would try this for about 1 week, hoping that she improves over this time. I would also recommend adding a supplement such as 1 tablespoon of bran, canned pumpkin, or metamucil as a fiber source to increase the stool consistency.You can also consider giving 15mg of Pepcid A/C (famotidine) by mouth every 12 hours for 5 days for stomach upset. You can purchase this over the counter.I hope this information helps!
