If you think it is the fiber in the Cheerios that is helping, you could try adding a little plain canned pumpkin. But, you want to be careful not to add too many unbalanced things to your dog’s diet. Only 10 to 15% of calories should be unbalanced toppers and treats. You could be feeding a little too much too. That will sometimes cause loose stools.
Also, I believe Orijen is a very rich grain free diet. I’m surprised you would feed it to a dog with a tendency to have pancreatitis. In addition, have you seen the FDA warning about grain free boutique foods?
