I was also told to get a high protien diet with little or no grains because dogs are naturally carnivores. Try going to a specialty dog food store, I find that the staff more knowledgable about the ingredients in dog food.
A little fact about Orijen: The town where it's made is about 20 mins from here and if the wind is blowing the right way....the whole town smells like dog food! :biglaugh:
