Watch your dogs, especially your Rotties, for symptoms of food allergies... dry, flaky, itchy skin around the rump, primarily. Authority foods do contain corn and/or wheat, and corn and wheat are common allergens for rotties.... and many other breeds.

PetSmart employees recommend the Authority brand of dog food because PetSmart owns that brand... it's a good way to increase corporate profiteering, but not necessarily a good food.
