Hello - diarrhoea can happen secondarily to other conditions, perhaps including liver disease or pancreatitis, Addisons disease, EPI and various autoimmune diseases. I wonder whether more tests might be on the cards. Good questions for your vets include, 'What possible causes haven't been ruled out yet?' Then, 'Could any of these be urgent?' and 'Which would be the most common?' and 'Which are easiest to rule out?' because the answers to those questions will often determine which tests your vet chooses to do first. Stress is often a tricky one and may be worth a discussion.
