The page you linked illustrates a few points I have tried to make before. A dog of a certain size is used to eating a certain amount of food. For my dog, Nutro has the right kcals, etc, (or "density") for the amount of food he eats. Some, not all dogs, depending on their metabolism may not do as well on a calorie-dense food, and metabolism can be affected by breed. For example, Dobies can have a taurine deficiency. Or, all the other ingredients that make a food "holistic" may not be as agreeable to the system. Just because a gray wolf can eat a berry off of a bush doesn't mean your dog can, regardless of genetic similarity. So, my second point is that calorie dense foods may be better, on average, for smaller breeds, who can only eat so much. Then again, a number of "holistics" eschew corn because it is branded as the bad grain and rice because many lay people have the opinion that rice has no nutrients and instead use barley, which has been known to be an allergen far more often than corn or rice.
