What happens
Sweetcorn kernels themselves are not toxic and are a normal ingredient in many dog foods, so a few plain kernels are a harmless treat. The real danger is the cob. A corn cob does not break down in the gut and is exactly the wrong size and shape to cause a blockage, which can become a life-threatening emergency needing surgery.
How much is safe?
A spoonful of plain, cooked kernels off the cob is a fine occasional treat. There is no need for more, and the kernels should stay within the daily treat allowance. The cob itself is never safe in any amount.
How to prepare it
Strip plain, cooked kernels from the cob and serve a small amount with no butter or salt. Never give a dog a whole cob to chew, and be careful at barbecues and picnics, where discarded cobs are a common cause of emergencies.
Symptoms to watch for
Plain kernels rarely cause problems beyond mild gas if a dog eats a lot. A swallowed cob is the emergency - watch for vomiting, straining, a painful or bloated belly, loss of appetite and lethargy, which can appear over hours to days.
When to call the vet
If your dog eats a corn cob, or part of one, contact your vet straight away, even before symptoms appear - cobs cause dangerous blockages and early action matters. Vomiting, straining or a painful belly after a cob is an emergency.
