Hello, sorry to hear about Paigee. It most instances, bloody diarrhea is caused by inflammation of the GI tract. If frank blood, this is most often a large intestine inflammation, if dark blood, then this could be from the stomach or small intestine. Most often, inflammation of the GI tract is caused by some form of dietary indiscretion and is self limiting to a few days. If signs worsen, if she develops vomiting, innapetence, pain or lethargy, then she should be seen by a veterinarian. If she has frank blood diarrhea, she should be seen by her veterinarian. In the interim, you may try to feed her a bland diet of plain white rice, skinless and boneless boiled chicken, and low fat cottage cheese for the next 3-5 days. Hope this helps and best of luck.
