Corn on the cob — Food safety facts
Do not feed · Dogs · full breakdown on the linked food page
Dangerous for dogs: the cob is a classic cause of intestinal blockage and can be fatal. Kernels off the cob are fine.
Dogs are rated “Do not feed” and cats “Feed with care”. If both share the house, go by the stricter of the two when you decide what to hand over.
Corn on the cob should not be given to dogs at all. Even a small amount can do harm, so there is no portion small enough to be safe.
Do not induce vomiting and do not give milk or oil to “dilute” it. Note the food and roughly how much was eaten, then call your vet or a pet poison hotline and follow their advice on whether to bring the pet in straight away.
Why these cautions matter
Rich, fatty food is the classic trigger for pancreatitis, a painful inflammation of the pancreas that usually needs veterinary treatment rather than rest alone.
Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
Corn on the cob has no place in everyday feeding: keep the rest of the day's food unchanged after this and watch the next walk and the stool that comes with it.
