The quick answer: Yes, dogs can eat plain corn that has been removed from the cob.
Benefits of corn
There’s nothing like freshly grilled corn on the cob, hot off the barbecue on a sunny summer day. Corn is sweet and crunchy, and the good news is that your dog can enjoy it too.
Corn is commonly included as an ingredient in dog foods and it’s safe to feed to dogs so long as they are not allergic to it. The way to share corn with your dog is plain, fresh corn kernels that have been cut off the cob. Corn is a good source of protein, carbohydrates, fiber, linoleic acid, and antioxidants. Though your dog gets the nutrients she needs from a balanced dog food, it is safe to share a bit of corn with your pup as a snack.

Cooked corn kernels are generally safe but could pose a choking hazard for small dog breeds that have a habit of scarfing down their food. The most dangerous part of corn is the cob. Never allow your dog to eat corn directly off the cob. Though it may seem impossible to swallow, when a dog is hungry enough, they can whittle a corn cob down to a size just small enough to swallow, but far too big to pass through the digestive system. A swallowed corn cob can cause an airway obstruction or a partial or complete intestinal obstruction, requiring emergency surgery to remove. Symptoms include difficulty breathing, vomiting, diarrhea, pain, whimpering and restlessness. Seek immediate veterinary care if you suspect your dog was involved with the disappearance of a corn cob.
Corn with added butter, salt, spices, or cheese shouldn’t be given to your dog because it can cause potential health problems. Added fats can cause digestion issues like vomiting, diarrhea or even pancreatitis. Salt can lead to dehydration, and other spices may contain ingredients that are toxic to dogs, like garlic and onion powder. Plain cooked corn is the safest and healthiest to share with your dog.
