Nutrition facts about corn for dogs
Corn itself can be safe for dogs if they just eat the kernels, or certain products made from corn. In fact, many commercial dog foods use corn as a healthy source of certain nutrients.

Additionally, corn contains important vitamins and minerals such as zinc, magnesium, copper, iron and B vitamins that are necessary for daily biological functions. Corn cobs, however, are a different story.
Are corn cobs good for dogs?
Corn cobs are not good for dogs and can pose serious dangers to them if ingested. The problem with corn cobs is that they are extremely fibrous, made from a plant material called cellulose that is difficult to digest and break down. Corn cobs are also just the right shape to be small enough for most dogs to chew on, but too big to easily pass through their digestive tract. This leads to the following risks:
Choking hazards: Due to their size and shape, it is easy for most dogs to chew on corn cobs. Because they are made of plant fiber, dogs with strong teeth and jaws can often break them apart. Large pieces that they attempt to chew and swallow can become a choking hazardopens in a new tab.
Intestinal blockage: If a dog succeeds in swallowing pieces of corn cobopens in a new tab, this may lead to a life-threatening condition known as an intestinal blockage. The pieces of corn cob are not broken down in the stomach but pass through the digestive tract whole. Often, they are too large to pass through the narrower parts of the intestines and can get stuck. This leads to serious pain, vomiting, and other symptoms. Emergency surgery is almost always required to remove the blockage.
Digestive upset: Even if a dog is able to chew up the corn cob into small bite-sized pieces, they can still cause problems. These highly fibrous fragments can be sharp and irritate the digestive tract on their way down. All of that excess fiber can also cause opens in a new tabbloating, gas, vomiting, or even diarrhea.

Are corn cobs completely safe for dogs?
Corn cobs are not completely safe for dogs and in fact, pose many dangers. They should be kept far out of reach. Your dog should be carefully supervised at barbecues and other parties where food may be accidentally left at their level. Be sure to keep trash well-containedopens in a new tab; dogs have been known to tear into trash if they smell delicious scraps, too.
If you suspect your dog has eaten a corn cob, or any other inedible materials, such as skewers, fruit pits, bones, plastic, and the like, be sure to contact your vet right away. Even if your dog is acting fine initially, it is better to be proactive than to wait until they are sick. Sometimes, if dogs are seen right after eating something, a vet can induce vomiting, or use an endoscope to remove it from the stomach before it has a chance to get stuck lower in the intestines. This can save your dog from more serious discomfort and more invasive surgery.
If your dog does show signs, including vomitingopens in a new tab, refusing to eat, lethargy, and/or an upset stomach, be sure to get to an emergency clinic right away. Foreign objects like corn cobs often need to be surgically removed and the longer they are stuck, the more damage they can do.
