Can dogs eat Sweetcorn?
In small amounts, with care
In moderation, kernels only - sweetcorn off the cob is safe and appears in plenty of dog foods. The cob is the danger: corn cobs are one of the most common causes of gut blockage vets see.
What happens
Sweetcorn kernels are not toxic - they are a normal ingredient in many complete dog foods, and a spoonful of plain kernels is a harmless treat. The cob is a different story entirely. A corn cob does not break down in a dog's stomach, and its size and shape make it one of the classic causes of intestinal blockage, an emergency that frequently ends in surgery. Barbecues, picnics and kitchen bins are where most cob incidents start, because a chewed cob smells exactly like dinner to a dog.
How much is safe?
A spoonful of plain cooked kernels, off the cob, as an occasional treat is plenty. Frozen sweetcorn, cooked and cooled, works fine. There is no safe amount of cob - not a chunk, not a stub, not a nibbled end.
How to prepare it
Strip the kernels from the cob and serve them plain - no butter, no salt. Bin cobs somewhere secure the moment they are finished, especially at barbecues, and never hand one over as a chew, however convincing the begging.
Symptoms to watch for
Plain kernels rarely cause more than a bit of wind. A swallowed cob is the emergency: vomiting, straining, a painful or swollen belly, loss of appetite and lethargy, appearing over hours to a couple of days as the blockage takes hold.
When to call the vet
If your dog eats a corn cob or any part of one, call your vet straight away, even if they seem completely fine - do not wait for symptoms. Blockages are time-critical, and acting early is the difference between simple treatment and surgery.

Common questions
Can dogs eat tinned sweetcorn?
Only the no-added-salt kind, drained and rinsed. Standard tinned sweetcorn is salty, so plain frozen sweetcorn, cooked and cooled, is the better choice.
How do I know if a corn cob is stuck in my dog?
Vomiting, straining, a painful or swollen belly, loss of appetite and lethargy over the hours and days afterwards are the classic signs. Do not wait for them - if you know a cob has gone down, call your vet immediately.
Can dogs eat sweetcorn every day?
There is no need. Kernels are safe in moderation, but they are starchy and offer little that a complete diet does not already provide. Keep sweetcorn to an occasional spoonful.
