There can be many causes for blood in diarrhea or stools, including food intolerance, food allergies, intestinal parasites, dietary indiscretion, bacterial or viral infection, hemorrhagic gastroenteritis, stress colitis, autoimmune disease, systemic disease (liver, pancreas), toxic exposure, bleeding/clotting disorders, cancer, rectal polyps, among others. I would recommend that Ricky be evaluated by a vet for diagnosis and appropriate treatment. Some of these possible illnesses can get worse very quickly and can become life-threatening.
