Stress can cause pancreatitis. My vet said there is a dog at his clinic that gets pancreatits every time he is boarded. So sad and so painful for the dog. Zeus has been battling pancreatits, but we have no idea why his started. I do know that you shouldn't give Bentley a lot of fat or protein, since this makes the condition worse. Zeus is on a very strict diet of prescription food. Hope your little one is feeling better soon!
