No - Corn on the Cob is toxic to dogs
No - never give a dog corn on the cob. The kernels are harmless, but the cob is one of the most common causes of intestinal blockage vets see, and it will not break down.

How much is safe?
None. Corn on the Cob is never safe for dogs - not even a little.
No amount of cob. Plain sweetcorn kernels cut off the cob are safe in moderation.
Symptoms to watch for
Repeated vomiting, especially after drinking, loss of appetite, lethargy, a hunched or painful abdomen, straining without producing stools, and general restlessness. Signs may take a day or two to appear.
Think they have eaten Corn on the Cob?
Straight away if you know or suspect your dog has swallowed cob, even a short piece and even if they seem fine. A blockage caught early is far simpler to treat than one caught late.

What happens
This is a mechanical danger rather than a poisoning. A cob is exactly the wrong shape and size to pass through a dog's intestine, and it does not soften or digest. It lodges, blocks the gut, and usually needs surgery to remove. Dogs also tend to swallow chunks whole rather than chewing them, and barbecue leftovers in an accessible bin are the classic route.

Common questions
My dog swallowed a corn cob - what should I do?
Call your vet immediately, even if your dog seems fine. Cobs do not digest and are a leading cause of intestinal blockage. Do not wait for symptoms, and do not try to induce vomiting unless your vet tells you to.
Can dogs eat sweetcorn kernels?
Yes, plain kernels off the cob are safe in moderation and appear in plenty of dog foods. It is only the cob that is dangerous - and it is dangerous enough to be worth being strict about.
