What are some facts about Corn?

Many believe that corn doesn’t add any nutritional value to dog food, but corn is an inexpensive source of carbs, linoleic acid, fiber, antioxidants, vitamins, and even protein. 

Corn can be found in many kibble recipes because it helps keep pet food affordable. Without corn, kibble would be a lot more expensive. 

While corn may be part of a well-balanced diet, it shouldn’t make up a large portion of a dog’s diet.

Unfortunately, there are a few myths perpetuated by the dog food industry, embellishing the nutritional benefits of corn.

There is nothing exceptional about corn, aside from the fact that it is reasonably priced and isn’t just empty calories.

Here are other nutritional facts about sweet corn:

  • Corn has a high glycemic index of 52, which makes it unsuitable for dogs (and humans) with diabetes. 
  • Beef causes more allergic reactions than corn does, followed by dairy and wheat. 
  • Whole corn is not highly digestible for dogs because dogs don’t digest fiber very well.
  • Corn offers some protein, fat, and fiber but contains mostly carbs from starch.
  • Corn has a similar nutritional value as brown rice or barley.

Offering your dog corn or sweet corn kernels as an occasional treat is totally fine. Having corn listed as an ingredient in fido’s dog food is to be expected, as long as it’s not too high up the list.

The first three ingredients should always be meat-based protein and not any form of gluten.

How about grain-free diets? According to Dr. Freeman of Tufts University, grains aren’t the problem, but the quality of the ingredients used in dog food.

Health Benefits of Corn

Corn won’t win any awards as a good source of protein, but it does have some protein content

Corn also contains antioxidants that help support your pup’s immune system.

There are trace amounts of fatty acids, folate, vitamins A and K in corn. Still, it’s not so extraordinary that veterinary nutritionists would recommend giving corn to your dogs daily.

Whole corn can help your dog’s digestive system, especially if he has constipation because the cellulose shell doesn’t break down during digestion and would encourage bowel movements.

How to Know Which Types of Corn Are Safe

Aside from not letting your dogs eat corn on the cob, there aren’t any hard and fast rules when it comes to feeding corn.

How much corn can I give my dog?

When it comes to human foods, always view them as treats. How much corn to give your pooch is entirely dependent on individual dogs. 

For small, obese, or dogs that are sensitive to new foods, you might want to keep the amount relatively modest.

We’re talking just one or two kernels. On the other hand, if your dog loves it, feel free to top his kibble with just a handful of corn.

Is corn bad for dogs? As long as corn is given in moderation, it should be okay.

Dog breeds that suffer from obesity should stay away from sweet corn because of its high starch content. 

You should never give your dog corn on the cob unsupervised because it’s a choking hazard and can be dangerous if swallowed. Even a small piece of cob can cause intestinal blockage, especially in small dogs.

Food allergies or sensitivities may develop at any age, so just because your dog used to be fine with cereal grains, your dog’s stomach might one day decide otherwise. 

An allergic reaction often occurs immediately after your dog ingests a particular ingredient, whereas a food sensitivity might cause certain problems if fed over an extended period.

If your dog is allergic to corn, he will be excessively itchy after consuming corn and might vomit or have diarrhea.

What should I do if my dog accidentally ate a corn cob?

Eating corn in a cob can cause some serious damage to your pup’s digestive tract. It can cause intestinal blockages, which can be fatal.

Ensure you tell your vet about the corn cob because corn cobs don’t show up easily on x-rays.

Symptoms of an intestinal blockage include a loss of appetite, lethargy, vomiting, or lethargy. In addition, black, tar-like stools are a symptom of injury to the GI tract. 

You should seek medical help immediately if your dog exhibits these symptoms.

Plain popcorn is a wonderful low-calorie treat if given every once in a while. However, make sure you don’t give your dog any unpopped kernels as it may cause upset stomachs.

Also, it’s best to air-pop instead of popping them in oil.

When feeding corn, it’s best to give unbuttered and unsalted corn. This is because when a dog eats, they usually aren’t as picky as us humans!

Can Dogs Eat Canned Corn?

Yes, you can feed your pup canned corn since they mostly consist of kernels and no longer includes the cob. It’s also high in fiber but remember to give them small amounts.

Also, always check the labels before giving them to your pup. Not all canned corn products are created equal. Some canned corns are high in sodium which can lead to diarrhea and vomiting.

Many human foods can be beneficial to dogs, but there are also certain foods they should avoid. Some healthier snacks include carrots, blueberries, or green peas.
