Hi there. If Beau is on prednisolone to treat a chronic GI issue such as inflammatory bowel disease or something similar, then yes - lowering his dosage could certainly cause diarrhea or other symptoms to recur. If he was on it for something unrelated to this, then I would not expect decreasing his dosage to cause diarrhea "out of the blue" - so in that case, it's likely that there is some other cause.
