Well, im certain it is diet related. Today I took him off Orijen and Gave him boiled rice and overcooked oatmeal to help settle his tummy. His poop is firm. Go figure. Now goes the search for a new food.
We had some minor GI issues with two of our dogs, the most recent being the GSD pup. A raw diet did them wonders. Our other dog had skin issues until after we changed him to a raw diet. I'm not saying it's a miracle cure, but if you're careful, you can avoid a lot of useless and/or potentially harmful additives found in dog food today.
