Keep Corn on the cob to small, occasional amounts. Sensitive pets may react to it, and sugar- or fat-heavy foods raise the risk of obesity and pancreatitis.
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.
If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
