Oh dear! I'm afraid this sounds quite serious. Black, runny stool is often a sign of bleeding in the stomach or intestines, which is a life-threatening problem. A hard, bloated stomach could be caused by peritonitis (especially if Bruni has an ulcer that has perforated and is leaking into her abdomen), internal bleeding, cancer, liver failure, or heart disease. These symptoms warrant an emergency vet visit right away, so I would recommend taking her to your nearest veterinarian immediately. He/she can do some diagnostic testing if needed to help determine the problem and see what can be done to help her.
