What You Need to Know
Corn kernels are safe for dogs but the cob is extremely dangerous. Dogs often chew through the soft kernels and swallow large pieces of cob which then become lodged in the intestines. Unlike most objects that can pass through the GI tract the corn cob conforms to the intestinal shape creating complete blockage. Emergency surgery is almost always required. This is a genuine surgical emergency.
