How old is she??? How active?? And how much are you feeding??? Overfeeding can cause loose stools to begin with add to that the fact that Orijen can be very rich and you have a recipe for disaster... Before switching foods all together, I would try cutting back on the amount you are feeding. (Depending of course, on how much you are currently feeding). That being said: Acana is a great food that is made by the same company as Orijen. Just a little less rich and from what I understand easier on the wallet as well.
