Some pet foods advertise that they have “no corn” as if corn is a dangerous or “bad” ingredient for dogs. It’s not. Corn meal and ground corn in dog food is a good source of starch and an essential fatty acid called linoleic acid. Corn also provides several B vitamins, magnesium, potassium, and carotenoids like beta-carotene.
You needn’t shy away from a dog food that lists corn as an ingredient. In fact, unbuttered, unsalted popcorn even makes a good low-calorie treat for a dog.
