⛔ Unsafe Known to be harmful or toxic. Keep it away from your pet.

Corn cobs are unsafe for dogs. While not toxic, they pose a severe risk of intestinal blockage or perforation. The hard, fibrous structure does not digest well and can splinter, causing serious internal injury if chewed or swallowed.

🚨 Emergency: Yes — contact your veterinarian immediately.

💡 Why

Corn cobs are indigestible and can expand in the stomach, leading to life-threatening obstructions. They may also splinter, causing punctures in the intestinal wall. Veterinary consensus strongly advises against feeding corn cobs to dogs of any size.

🩺 What to do

  1. Remove the cob immediately if your dog has access to it.
  2. If your dog has chewed or swallowed a piece, monitor for vomiting, lethargy, or loss of appetite.
  3. Contact your veterinarian immediately if you suspect ingestion, as X-rays or surgery may be required.
Important: this is for reference only and is not veterinary advice. If your dog may have eaten or touched something dangerous, contact your veterinarian immediately.
