Correct!
The answer is: Corn on the cob
It is not corn kernels that are the problem for obstruction, but the cob. Cobs are very fibrous and tough to digest. They can lodge in the intestinal tract and cause life-threatening obstruction or rupture. It is also important to note that many dogs are allergic to corn; even though the kernels are digestible, your dog may not be able to tolerate it as a food (intestinal gas, discomfort, vomiting or diarrhea).
