Corn Cobs — toxicity in dogs

Call your vetApplies to: dogs.

Overview

Corn cobs are not chemically toxic, but they are a leading cause of intestinal obstruction in dogs. Because cobs are fibrous and poorly digestible, they can lodge in the stomach or small intestine and block normal passage of food. Symptoms may not appear immediately and can worsen over 24-72 hours. Any known cob ingestion should be treated as an urgent mechanical risk, not just an upset stomach.

Symptoms

Vomiting, abdominal pain, no stool, lethargy

Typical onset

Hours to days

What to do

Urgent vet exam recommended if swallowed.
