Corn

Also appears on labels as: ground corn, whole corn, whole grain corn, yellow corn, ground yellow corn, ground whole grain corn

Ground field corn, the same commodity grain used across livestock feed.

Watched ingredients get highlighted on every product panel you open.

Where it comes from: US grain elevators and mills.
Why it's in the product: Energy, some protein, and linoleic acid. Ground corn is genuinely well digested by dogs once it is cooked.
Safety and toxicity: Corn's bad reputation is mostly marketing. It is not a common allergen and it is not indigestible. The real risk is agricultural: corn is susceptible to aflatoxin, a mold toxin that has caused fatal pet food recalls, most recently in 2020 and 2021. Reputable manufacturers test incoming grain for it.
Interactions and who should be careful: Corn's glycemic load is worth discussing with your vet for diabetic pets, though total carbohydrate matters more than the specific grain.
