What it is

Corn grain, ground and cooked into the recipe. Cooked corn is digestible; whole corn passing in stool is the hull, not the nutrient fraction.

Why makers use it

It is one of the cheapest energy sources in the industry, which is precisely why it is used so widely.

What to watch for

Our rubric flags whole grain corn among the first ten ingredients as a formulation intent signal, not a safety one. Corn is not a common true allergen in dogs despite its reputation.
