Why Are Corn Cobs Bad for Dogs?

Corn cobs are dangerous for dogs primarily because of the risk of gastrointestinal blockage. Dogs canโ€™t digest the tough cob material, which can lodge in their intestines and cause a life-threatening obstruction. Even small pieces can cause severe damage or blockages.

How Much Corn Cob Can Dogs Eat?

Ideally, dogs should not eat corn cobs at all. Even a small piece can pose significant risks, and itโ€™s best to avoid giving them any. If you want to treat your dog with corn, ensure that it is removed from the cob and given in moderation.

Common Misconceptions

A common misconception is that because corn is a common ingredient in dog food, corn cobs must be safe too. This is not true. Unlike processed corn in dog food, corn cobs are hard and cannot be broken down by your dog's digestive system, posing a choking hazard and risk of blockage.
