Maize / Corn in dog food
Maize (or corn to us Brits) is widely used in dry dog foods as an alternative to grains like rice, oats and barley. Of all of the grains used in dog food, maize is certainly amongst the most controversial, with vocal critics and supporters in equal measure.
It has to be said though that many of the most ardent supporters of maize are from within the pet food industry. They correctly argue that maize is a good quality, nutritious carbohydrate source with a comparable nutritional profile to grains like oats and barley.
Critics of maize, on the other hand, claim that it is harder for dogs to digest and is therefore much more likely to lead to food intolerance or allergies. Many canine nutritionists and some vets now recommend avoiding maize based diets altogether.
