Query: Not a quality dog food

This dog food has all the ingredients you don't want in a dog food - corn, by-products, etc. For about the same price, Diamond has their Naturals line that is MUCH BETTER in terms of quality. Diamond Naturals Puppy food doesn't have corn or by-products.I honestly don't know why Diamond puts out this awful dog food when they can make quality ones for right about the same price - given the choice, who would take the one for less quality?Our puppy was on this when we got her, we bought a small bag and slowly changed her food to the Diamond Naturals for Large Breed puppies, and the difference is fantastic. We'll stick with the Naturals, and never have her go back to this variety.
