I don't think so, unless you're considering moisture to be a
nutrient. It's a critical part of a diet, obviously (living
things will die without water before they'll die without
food), but it's generally not included in the list of
macronutrients. Also, dry matter calculations level the
playing field, so to speak - it's a way of comparing foods
with different moisture contents.

Think of it this way: if your dog eats 2 cups of dry food
and drinks 2 cups of water, is she really getting less
macronutrients than if she eats 2 cups of dry food and
drinks one cup of water? On an "as fed" basis it's less.
On a dry matter basis it's the same.

But "as fed" is how the individual animal is
receiving it. When it comes to nutritionally
linked illnesses, that is a major component.
