This is very concerning, the dark colour indicates she may have a bleed in the gastrointestinal tract. Urine blood tests for medical issues such as kidney and liver disease may be required as well as an abdominal x-ray for any signs of obstruction or constipation. Intravenous fluids may be required for dehydration also. Please schedule a recheck as soon as possible
