Benefits of Corn for Dogs

Benefits of Corn for Dogs

Including corn in your dog’s diet can have a beneficial effect on their overall health and well-being. Let’s take a look at the biggest benefits of feeding your dog corn:

1. Corn Supports a Strong Immune System

Corn is rich in vitamin C, a powerful antioxidant that is involved in many functions inside your dog’s body. Vitamin C supports a strong immune system and can help keep your dog protected against diseases. 

This vitamin also helps reduce inflammation and can be extremely beneficial for dogs who suffer from allergies. And since vitamin C helps in the production of collagen it can improve your dog’s joint and bone health (source). 

2. Corn Promotes Good Digestion

Besides being safe for your dog to eat, corn can also do wonders for your pup’s digestive system. This cereal grain is a great source of dietary fiber which promotes good digestion and can regulate your dog’s bowel movements. 

Feeding your dog corn can also help keep them full for longer between meals and curb hunger pangs. 

3. Corn Promotes Eye Health

Yellow corn is a great source of antioxidants carotenoids, lutein, and zeaxanthin which are good for your dog’s eye health. These antioxidants help prevent the lens damage that leads to cataracts and can help keep your pup’s eyesight sharp in senior years. 

4. Corn Supports Muscle Health

Corn is also a great source of potassium which is an essential mineral and an electrolyte involved in several functions within your dog’s body. Potassium helps in the functioning of electrical charges in your dog’s heart, muscles, and nerves.

Dogs who lack potassium may appear tired all the time and have a decreased appetite. If you notice any of these symptoms take your pooch to the vet so they can check your dog’s potassium levels. 

Risks of Corn for Dogs

Risks of Corn for Dogs

By now it’s fairly clear that dogs can eat corn and experience certain benefits. However, like with any other food, dogs can also experience side effects after eating corn.

The biggest risks of feeding corn to dogs are:

1. Choking Hazard 

While giving your dog corn on the cob might seem like a good idea, a piece can get stuck in your dog’s throat and pose a choking hazard. Furthermore, eating corn cobs can also cause a serious intestinal blockage that may require surgery. 

Due to their miniature size, small dogs are at a higher risk of choking on a piece of cob so keep any corn on cobs beyond your dog’s reach. 

If you suspect that your pooch managed to ingest the cob look for signs of dehydration, lethargy, repeated vomiting, diarrhea, and loss of appetite. If your dog shows any of these symptoms take them to the emergency veterinary clinic or call your vet right away. 

 2. Allergies

Food allergies are much rarer in dogs than in people, but some dogs might be allergic to grains or have sensitivity to corn. If your dog has a confirmed allergy to corn, they shouldn’t eat sweet corn or any other type of corn for that matter. 

If you suspect that your pooch might be allergic to corn or some other ingredient from their food take them to the vet for a full check-up. Figuring out what type of food your pup is allergic to can significantly improve the quality of their life. 

How Much Corn Can I Give My Dog?

While plain corn kernels are safe for dogs to eat as treats, you should talk with your vet before feeding any new foods to your dog. Like most other fruits and vegetables, dogs can eat corn as a treat in moderation. 

And like any other treat, corn shouldn’t make more than 10% of your dog’s daily calorie intake (source). 

If you have trouble figuring out how much corn you can feed your dog, consult your vet or a canine nutritionist. They will be able to tell you exactly how much corn can your dog have based on their age, size, and nutritional needs. 

How to Feed Corn to Your Dog?

There are many ways you can feed corn to your dog, just make sure to remove the cob first. Only feed plain and unseasoned corn kernels to your pooch to avoid intestinal obstruction and choking.

  • Cook the corn on the cob and feed kernels as treats
  • Use cooked corn kernels as a topper 
  • Mix cooked kernels with your dog’s food
  • Grill the corn and feed kernels as treats to your dog
  • Roast the corn on the cob and mix kernels with your dog’s food


One of the most popular cereal grains in the world, corn is full of valuable nutrients your dog needs to stay healthy and thrive. Rich in essential vitamins, minerals, and antioxidants, corn can boost your dog’s immune system and improve their eyesight. 

While corn kernels are completely safe for dogs to eat in moderation, don’t let your dog near corn cobs. Corn cobs pose a choking hazard and can cause an intestinal obstruction if swallowed so keep them far away from your pooch.
