How Much Cornflakes Are Good for Dogs?

Cornflakes are just okay food for dogs, as they are high in carbohydrates and barely minimal in protein and other nutritional values. You need to be careful with them. First, rule out anything your dog may be allergic to, and check the label and the flavor. Many dogs are allergic to chocolates, nuts, raisins, and a sweetener, xylitol. Plain cornflakes should be preferred over any other flavor. Also, no milk!

What Are The Nutritional Benefits of Cornflakes?

  • Cornflakes lack nutritional value; they are very high in carbohydrates.
  • Cornflakes contain 89 calories, 21g carbs, and 182 mg sodium (one cup 25 g)
  • Cornflakes are rich in folic acid, which is essential in synthesizing blood cells.

What Happens if A Dog Overeats Cornflakes?

Although cornflakes are safe for dogs, they are devoid of nutritional value. Many brands of cornflakes are full of sugar which can be hazardous for your dog’s health. If your dog overeats it, it can lead to weight gain, diabetes, and tooth decay. It feels more like an empty meal than a meal full of protein and fat. It’s not a good balance of nutrition for dogs.
