CAn someone out there shed some light on this for me? My 9 year old yorkie had an attack of pancreatitis about 3 months ago. She was put on special prescription food, no table scraps and has been doing well. Out of the blue, today she has very loose stools with blood. My vet is low key and just gave me flagyl to give her. He assumes it will clear up in 3 days. I'm a wreck. Any suggestions?
