Sweetcorn is a versatile people-snack that comes in so many forms, including kernels, popcorn and corn chips. But is it a treat you share with your dog? In this blog post, we’ll discuss if it's a safe treat for our furry friends to enjoy. We’ll also explore which forms of sweetcorn are okay for your pooch, and which you should avoid.

Can dogs eat sweetcorn?

As long as your dog isn’t allergic to this kind of grain, yes, dogs can eat sweetcorn! It's a versatile, common ingredient that you’ll even see in lots of different commercial dog foods. To keep things safe for your dog, only give them plain, cooked sweetcorn in moderate amounts. You can feed it to your dog on its own, or as an ingredient in a treat or their food.

 Can dogs have frozen sweetcorn?

Absolutely, dogs can enjoy frozen sweetcorn! It can be a great cool and crunchy treat, especially on a warm day. Freezing sweetcorn doesn't take away its nutritional value, so it's a safe and refreshing option for your pooch. Just make sure it doesn’t have any added seasonings or butter. You can feed the frozen sweetcorn kernels to your dog, or wait for them to defrost before you give them to your pooch.

Is sweetcorn good for dogs?

Because sweetcorn is a treat, your dog probably won’t get all of the nutritional benefits. But there are certainly good things about giving sweetcorn to your pup.
Sweetcorn has linoleic acid, which is an important omega-6 fatty acid which keeps their skin healthy and fur shiny. And it's not just sweetcorn though. Other grains like wheat, oats, rice, and barley provide protein and important vitamins and minerals too. These grains, including sweetcorn, have carbs that are easy to digest, which gives your dog energy to stay active.
Sweetcorn and other veggies (like carrots) should be a treat and not necessarily a staple in their diet. While they have nutritional benefits, we recommend you limit how much sweetcorn you give your dog. As a general rule, treats shouldn’t be more than 10% of your pup's daily total calorie intake. This helps keep up a balanced diet and your dog’s overall health, and prevent obesity.

Is sweetcorn safe for dogs?

Sweetcorn is safe for dogs when served in moderation and served plain. It contains some nutritional value, providing carbs, fibre, and small amounts of vitamins and minerals. 
However, there are exceptions. Dogs with allergies or sensitivities might react to sweetcorn, leading to digestive issues or skin problems. Additionally, while plain cooked sweetcorn is safe, sweetcorn on the cob can pose risks like choking or intestinal blockages. It's crucial to remove sweetcorn kernels from the cob before offering them to your furry friend.

What age can dogs eat sweetcorn?

Puppies can generally start eating small amounts of plain, home-cooked sweetcorn once they’re fully weaned and transitioned to solid foods. But, it's important to introduce new foods gradually, monitoring your puppy for any bad reactions. Always check with your vet before making significant changes to your puppy's diet, as their nutritional needs can vary based on breed, size, and health.

 Can dogs have popcorn?

As an occasional treat, dogs can have plain, popped popcorn. When sharing popcorn with your dog, keep portion sizes very small. Also avoid giving them sweet or salty popcorn, or popcorn with butter or other fatty ingredients. It’s best to steer clear of microwave popcorn bags, given the additives, seasonings, and the possibility of popcorn being coated in butter or oil. Too much butter and salt in particular can lead to tummy upsets, diarrhoea, and vomiting in dogs. To make sure it’s free of additives, it’s best to home-cook any popcorn you offer your pooch.
Watch out for unpopped corn kernels at the bottom of the popcorn bowl, as they can pose a choking hazard to dogs, especially smaller breeds. Remove any unpopped kernels so your dog doesn’t try to snack on them. Just like humans, popcorn can get stuck in your dog’s teeth so clean their teeth after having any.

Can dogs eat corn flakes? 

Corn flakes, like other processed cereals, should be avoided. Although plain cornflakes aren’t usually toxic, they aren’t a healthy option for your dog because they’re high in carbs and sugar. These breakfast flakes don’t have much nutritional value for our furry friends. It’s better go give your pooch a treat that’s specially formulated for dogs instead.

Can dogs eat sweetcorn on the cob?

Dog’s shouldn’t eat corn on the cob. The cob can cause serious risks to their health. If your dog eats the cob, it can cause bowel obstructions, choking, and other problems. Always remove the kernels before giving them to your dog.

Can dogs eat corn chips?

While corn chips aren’t toxic to dogs in small amounts, they’re not an ideal treat. There are lots of reasons why you should be careful about giving corn chips to your dog. Namely, they’re high in salt and fat which is bad for your pup’s health.

High in salt

Most corn chips are high in salt, which isn’t good for dogs. Too much salt can lead to salt poisoning, which has symptoms like vomiting, diarrhoea, lethargy, and tremors. In severe cases, it can be life-threatening. Corn chips also often contain artificial flavours, preservatives, and other additives that aren’t good for dogs. Some dogs are sensitive to these, which can lead to digestive issues or allergic reactions.

High in fat

Some corn chips are fried or coated in oil, making them high in fat. Too much fat can cause obesity. It may also lead to pancreatitis, a painful and potentially serious inflammation of the pancreas.

Choking hazard

Corn chips, especially if they’re big or particularly crunchy, can be a choking hazard to dogs. Especially small breeds, or dogs that don’t chew their food and tend to gobble down their treats.

Sweetcorn allergies

Even though it’s uncommon, it’s
that some dogs can be allergic to sweetcorn. If your dog has other food allergies or sensitivities, it's best to avoid giving them any food containing sweetcorn. Talk to your vet and get more advice on what they can and can’t eat.


Sweetcorn is safe and healthy for your pooch to enjoy in moderation. Your pooch can enjoy sweetcorn in moderation, and it can be used as a treat when plain-boiled, steamed or air-popped. More processed forms like sweetcorn flakes or chips aren’t healthy for your dog so keep them away from these types of corn snacks. Remove the kernels from the cob and you’re good to go.
