Warning Signs & Symptoms

Alkaline batteries: caustic burn injuries to mouth, esophagus, and digestive tract. Lithium button batteries: electrical current causes severe tissue necrosis and burns — particularly dangerous. Heavy metals: lead, mercury, cadmium poisoning with absorption.

If Your Dog Ate This

If your dog swallowed, or may have swallowed, any battery, including a button or coin battery from a remote, watch, key fob or hearing aid, take your dog to your vet or an emergency vet clinic right away, even if your dog seems fine. Button batteries can burn through the throat or stomach within hours, so do not wait for symptoms, and call ahead so the clinic is ready. If your dog chewed or punctured a battery and you believe none of it was swallowed, still call your vet or an emergency vet clinic right away and arrange for your dog to be checked, because leaking battery contents can burn the mouth, tongue and throat, and these burns are not always obvious at first. If you cannot account for all of the pieces, treat it as a swallowed battery. Do not try to make your dog vomit, because the battery or its contents can cause more burns on the way back up. Bring the packaging, a matching battery or any remaining pieces so the vet knows the type and size; the vet will decide whether an X-ray or other tests are needed.

What You Need to Know

Batteries present multiple serious dangers to dogs. Chewing a standard alkaline AA or AAA battery releases potassium hydroxide — a highly caustic substance that burns tissue on contact. Small lithium button batteries are the most dangerous — they generate an electrical current when lodged in tissue causing severe necrotic burns within hours. This is a genuine emergency regardless of battery type.
