The short answer is yes, dogs can eat corn. You’ve probably even noticed it in commercial dog food, especially if you’re searching for grain-free formulas. Corn is a known carb source, as well as high in protein and vitamins, including antioxidants.

Unless your dog is allergic, corn is not toxic or generally harmful. Plain corn – meaning without salt, butter, pepper, paprika, Cojita cheese, or any other additional ingredients – is okay to feed to your pup and should not cause problems. If your dog is allergic to corn, you’ll see a reaction immediately in the form of hives, itchy skin, or an upset tummy.

Corn on the Cob

Never feed your dog corn on the cob; the cob itself is a choking hazard and can obstruct your pup’s body at different points along the digestive tract. Due to their size, corn cobs can be difficult to pass and can cause partial or complete intestinal obstruction, which could require emergency surgery to remove. Even large dogs can have difficulty passing a cob. Signs of trouble include vomiting, diarrhea, pain, straining while going to the bathroom, whimpering, and restlessness. If you notice these symptoms, get to the vet immediately.

Can Dogs Eat Popcorn?

Dogs can eat popcorn as long as it’s plain – that means no salt, butter, or the crazy microwavable concoction – popcorn is a good treat every now and then. Popcorn is high in fiber and carbs which can provide some extra energy, if your pup is not diabetic. Pieces that don’t completely pop and full kernels can cause stomach problems or get stuck between teeth, so just make sure you pull those pieces or kernels out, and never leave a popcorn bag unattended for fear of suffocation.
