Cornflake cereal is a staple here in the United States, filling kitchen cabinets with its delicious flakes fortified with some nutrition, such as fiber, vitamins, minerals, proteins, and carbs1. However, have you ever wondered if cornflakes are good for your pooch?

Cornflakes may have vitamins and minerals, but it also has sugar. With that said, you can sparingly give your dog cornflakes in small portions.

Read on to learn more about cornflakes and dogs and whether or not it’s safe to feed your pooch.

Can Dogs Eat Cornflakes?

To answer this question, let’s talk about what is in cornflake cereal. Cornflakes are derived from milled corn2, and if your pup has a corn allergy, you’ll need to avoid giving your dog cornflakes3. The cereal also has sugar and is low in protein, which does not provide nutritional benefits for dogs.

Sugar is bad for dogs, especially dogs with diabetes, and cornflakes are relatively high in sugar5. However, as long as your dog isn’t diabetic, you can give your dog a few cornflakes on occasion as a treat but do so sparingly. Also, only give plain cornflakes on occasion and skip the frosted flakes, as they are even higher in sugar.

Can Dogs Eat Cornflakes and Milk?

While it’s ok to give your dog the occasional cornflake treat (unless your dog has a corn allergy), you should skip the milk. Milk can cause an upset tummy because most dogs are lactose intolerant.

Signs your dog is lactose intolerant are diarrhea, vomiting, loose stools, gas, and abdominal pain. In order to avoid these unpleasant symptoms, it’s best to just skip the milk.

What Cereal Can Dogs Eat?

As a rule, dogs really shouldn’t eat cereal because they should be receiving dog foods that cater to their specific nutritional requirements, and that goes for treats, too. As we’ve stated, it’s ok to let your dog have the occasional cornflake treat, but only sparingly and on occasion.

Some ingredients in cereal can be downright toxic for your dog, such as raisins and macadamia nuts. Some cereals are also high in fiber, which can be too much for your dog’s digestive system. It’s best to stick to your dog’s healthy treats instead of giving any cereal. However, cornflakes are ok but only on occasion.

Tips for a Healthy Diet for Your Dog

Since we are talking about cereals and cornflakes, it’s vital to never replace your dog’s regular food with any type of cereal. A dog requires food that is complete and balanced, which means providing the correct amount of proteins, fats, and carbohydrates, followed by essential vitamins and minerals.

When in doubt, you can always seek your veterinarian’s advice on what food to feed your dog for optimal nutrition.

Final Thoughts

Many people love a bowl of cornflakes in the morning, and your dog would probably love it, too. While it’s ok to give your dog the occasional cornflake treat (as long as your dog is not diabetic), it’s best to stick to healthy treats.

If you do decide to give your dog an occasional cornflake treat, ensure it’s not frosted flakes, and only give a few on occasion. Always feed your dog a complete and balanced diet, and avoid toxic ingredients often found in some cereals, such as raisins, macadamia nuts, and chocolate.
