What Makes Cornflour Good for Dogs?

That’s not right because corn contains antioxidants, proteins, linoleic acids, and carbohydrates essential for the well-being of your dog. Cornflour forms a part of the dog food when mixed with other ingredients. The carbohydrates within the corn also provide the fiber that’s essential for your dog’s motility and gut health.
  • Corn contains antioxidants like Betacarotene, lutein, and Vitamin E that helps in protecting important cells against damage. It can, therefore, lower the chances of your dog contracting cancer, strokes, cataracts, arthritis, heart diseases, and atherosclerosis.
