Can Dogs Eat Corn?

Corn can be an occasional extra for some healthy dogs when prepared carefully, but it is not necessary for canine nutrition.
Preparation and safe serving
Offer a little plain cooked corn as kernels removed completely from the cob.
What to avoid
Never give a corn cob, even as a chew. Avoid butter, salt and onion or garlic toppings.
Health considerations
A swallowed cob needs prompt veterinary advice; obstruction may cause vomiting, abdominal pain or loss of appetite.
All treats combined should supply no more than 10% of daily calories; at least 90% should come from complete, balanced food. Start with a small taste rather than a bowlful. The appropriate portion depends on size, body condition, activity and the rest of the diet, not just the ingredient.
When to ask a vet
Supervise eating and secure leftovers and packaging. Stop the new food if digestive signs develop. Persistent diarrhoea, abdominal pain, blood, weakness or inability to keep water down warrants veterinary assessment. Tell the clinic what was eaten, the ingredients, the amount and the time; do not induce vomiting or give home remedies unless instructed.
FAQ
Is corn necessary in a dog’s diet?
No. Complete, balanced dog food and fresh water provide the essentials. Extras are optional and may be unsuitable for some dogs.
What if my dog becomes unwell after eating it?
Stop offering it and contact a vet about persistent or severe signs, a swallowed object or unsafe ingredients.
