Corn and dogs: the kernels are food, the cob is a surgical emergency waiting
Safe with preparation
Plain corn kernels cut off the cob can be offered in moderation; the cob and husk are the obstruction risk and should never be given or left within reach.
Fine once the unsafe parts are removed.
Yes for the kernels, never for the cob. The AKC and PetMD clear plain corn kernels cut off the cob as an occasional treat, and both identify the cob and husk as choking and intestinal obstruction hazards. Butter, salt, onion, garlic and flavoured corn products put the dish outside that verdict.

If your dog has already eaten corn
Offer only a small plain amount; stop if gastrointestinal upset occurs. For prescription diets or medical conditions, ask the veterinarian first.

Which form of corn the sources actually cleared
Corn is the clearest food-versus-object split in this batch. The kernels are cleared; the cob they grow on is one of the classic obstruction cases in small-animal practice, and the husk goes with it. A corn cob is almost perfectly sized to pass the stomach and lodge in the intestine, and it does not break down. That is why a barbecue plate, a compost bin or a bin bag left accessible is a more realistic hazard than anything you would deliberately feed.
Preparing corn for a dog
Cut or scrape the kernels off the cob and serve them plain, then dispose of the cob where the dog cannot reach it — not a kitchen bin with a swing lid, and not a garden compost heap. Take the dog's share out before butter and salt go on. Tinned and frozen plain kernels are the same kernels; creamed, seasoned and flavoured corn products are not.
What actually goes wrong
- cob and husk choking and intestinal obstruction
- calorie load
The kernel risk is ordinary: calories, and digestive upset if a dog eats a lot. The cob risk is in a different category altogether. An obstruction can require surgery, symptoms may take a day or more to appear, and there is no home management for it. If a dog has eaten a cob, that is a veterinary call the same day rather than a wait-and-see, regardless of how well the dog seems.
How much counts as too much
All treats combined should generally stay within 10% of daily calories for a healthy adult dog in ideal body condition; individual needs vary.
The table below is the WSAVA reference allowance, printed as published. It is not a portion of corn: it is the total treat-calorie ceiling that everything given outside meals has to fit inside. Average healthy adult dog in ideal body condition. A veterinary team should set the individual dog's daily energy requirement.

What these sources do not settle
The sources give a form and a hazard but no kernel quantity per dog. They also do not clear corn on the cob under any preparation, including cooked, buttered or cut into rounds — the rounds still contain cob.
