Can Dogs Eat Corn Cobs?
Safety Information
Corn cobs can cause intestinal blockage.
Important Notes
While corn kernels are safe, cobs are a choking hazard and cause blockages.
Why are Corn Cobs So Dangerous?
The primary danger of a corn cob is gastrointestinal obstruction. A dog's digestive system cannot break down the tough, fibrous material of the cob. If a dog swallows a whole cob or even large pieces of it, it can easily become lodged in the stomach or, more commonly, the small intestine. This blockage is a life-threatening emergency that prevents food and water from passing through the digestive tract. It can cut off blood supply to the surrounding tissues, causing them to die, and can even lead to a rupture of the intestine. An intestinal blockage almost always requires emergency surgery to remove. In addition to blockage, a corn cob can also be a choking hazard if a piece gets stuck in a dog's throat.
Signs of an Intestinal Blockage
- If you suspect your dog has eaten a corn cob, you must watch them closely for signs of a blockage. Symptoms may not appear for 24 hours or more and include:
- Vomiting (especially repeated vomiting)
- Loss of appetite
- Lethargy and weakness
- Abdominal pain or bloating (your dog may whine or yelp if you touch their belly)
- Straining to defecate or diarrhea
What to Do If Your Dog Eats a Corn Cob
If you know your dog has swallowed a corn cob, it is best to contact your veterinarian immediately. Do not wait for symptoms to appear. Your vet can advise you on the best course of action, which may include inducing vomiting (if safe to do so) or taking a "wait and see" approach while monitoring for the signs of obstruction.
The Bottom Line
The risk of a life-threatening blockage is too high to ever justify giving a dog a corn cob. Always dispose of them in a secure trash can that your dog cannot access.
Emergency Notice
If your dog has consumed corn cobs, contact your veterinarian or the ASPCA Animal Poison Control Center (888) 426-4435 immediately.
General Feeding Guidelines
Introduce new foods gradually to monitor for allergic reactions or digestive issues.
Treats and human food should make up less than 10% of your dog's daily caloric intake.
Always consult with your veterinarian before making significant changes to your dog's diet, especially if your dog has pre-existing health conditions.
