I know a teeny bit about that, one of my pups had pancreatitis and Lupus she has to eat nothing but WD vet food by hills(fiber). NOTHING else or she would not be here.Thing is...I am diabetic and just suffered acute gastritis..and have had pancreatitis before....so I limit what I eat DRASTICALLY. I also never want to weigh 280lbs ever again. I currently weigh 12.5 stone, and I'm even unhappy with that lol.
