Why?
Corn itself is safe for dogs to eat — it is a common ingredient in dog food. It contains fiber, protein, and essential fatty acids.
How much can dogs have?
A small amount of plain corn kernels. Plain only — no butter, salt, or seasonings.
What to watch out for
The COB is extremely dangerous. Dogs cannot digest it and it causes intestinal blockages that often require emergency surgery. This is one of the most common causes of dog surgeries in summer. Never let your dog chew a corn cob.
