The practical rule is to separate the kernels from the cob before your dog has access. A cob is not a serving handle or chew. The corn profile covers the food, but the most important preparation task is controlling what gets discarded.
Take the kernels off away from the dog
Use a stable board or dish to catch kernels, then put the cob straight into secured waste. AKC: corn and cobs distinguishes occasional plain kernels from cobs that can cause serious obstruction. Do not hold out an ear for the dog to nibble, even if you intend to take it away before the cob is eaten. The transition from nibbling to grabbing can be quick.
Check the food that stayed on the kernels
Butter, seasoning blends and sauces belong to the final recipe. Corn from a mixed skillet or street-corn dish is not a plain vegetable portion just because the kernels remain recognizable. Check garlic and other additions separately. Set aside plain kernels before finishing the human dish; that is more reliable than trying to wash a prepared mixture back into separate ingredients.
Count holders, skewers and foil too
At a barbecue, the discarded cob is only part of the cleanup. Collect corn holders and skewers as soon as ears return from the table, and keep used foil away from the dog. Use a designated return tray for reusable utensils so they are not accidentally thrown into a food-scented bag. Do the count before the dog is allowed near the serving area.
If a cob piece is missing, change the task
Suspected cob swallowing calls for prompt veterinary advice rather than another snack. Record the approximate length missing, whether it was chewed and when it happened. VCA: ingestion of foreign bodies in dogs describes swallowed-object assessment; a comfortable appearance immediately afterward does not tell you where the material is. Do not induce vomiting or feed bread to push an object through unless the veterinarian specifically directs treatment.

Frequently asked questions
Can I give a small section of cob?
No cob section belongs in planned feeding. Smaller size does not turn a hard, swallowed-object hazard into a recommended chew.
Are canned kernels and creamed corn equivalent?
No. Check ingredients and preparation. A sauce-based product has a recipe beyond the kernels, and its label needs a separate review.
