Can Dogs Eat Corn?
Why it’s a sometimes-food
Cooked corn kernels provide carbohydrates, protein, fiber and linoleic acid, and corn is a common, well-tolerated ingredient in dog foods. The real danger is the cob: dogs gulp it whole and it is one of the most common intestinal blockages vets see.
How to serve it safely
Serve plain cooked kernels off the cob, no butter or salt. Skip corn entirely if your dog has a confirmed grain allergy.
Warning signs to watch for
Cob ingestion causes vomiting, loss of appetite, straining and lethargy within a day or two as the blockage sets in.
When to call the vet
If your dog eats part or all of a corn cob, call your vet immediately even if the dog looks fine.
Common questions
Why is the cob dangerous?
Dogs rarely chew it. The swallowed cob swells and lodges in the intestine, usually requiring surgery to remove.
Is corn a common dog allergy?
No — beef and dairy top the list. Corn allergy exists but is uncommon, despite the marketing claims of grain-free foods.
