The AKC notes corn is a common dog food ingredient and safe off the cob. Cobs are hard to digest and the right size to lodge in the intestine.
Yes, in moderation
Corn kernels are fine for dogs in moderation, but never give a corn cob. Cobs are a common cause of intestinal blockages that need surgery. Keep plates and bins out of reach at barbecues.
This guide is general information, not a diagnosis. If your pet seems unwell, or you're worried, call your vet.
What you need to know
How to offer it safely
- Plain kernels only, no butter or salt.
- A spoonful as a treat.
Treats, including human food, should make up no more than about 10% of your dog's daily calories. Our calorie calculator shows your dog's daily needs. Introduce any new food slowly and stop if it causes vomiting or loose stools.
If your dog ate some
- If your dog swallowed a corn cob or a large piece, call your vet even if it seems fine. Signs of a blockage can take a day or more to appear.
Signs to watch for
- Vomiting, especially repeatedly
- Not eating
- Belly pain
- Straining or not pooping
Collapse, seizures, difficulty breathing or pale gums are emergencies: go to the nearest vet straight away.
Other foods for dogs
Also yes, in moderation

Questions.
Will a corn cob pass on its own?
Sometimes, but cobs often cause blockages. Your vet may recommend X-rays or inducing vomiting soon after it was eaten.
