A Missing or Chewed Battery Is a Veterinary Emergency
PARTNER Editorial TeamIf your pet has chewed a battery, swallowed one or damaged a device and a battery is missing, contact a veterinarian or veterinary poison service immediately. Do not wait for visible mouth burns, and do not induce vomiting.
The ASPCA’s battery-safety explanation identifies several hazards: corrosive material from damaged batteries, swallowed objects causing blockage, and disc batteries causing burns even without being punctured. “It still looked intact” is therefore not reassurance after a possible button-battery ingestion.
Start the call while someone checks the device
Move the pet away from remaining batteries and device fragments when this can be done safely. Do not reach deep into the mouth or risk a bite to retrieve an object. Tell the clinic if breathing or swallowing is difficult or the animal is severely distressed.
If another adult is available, have them collect the device, battery packaging and visible remnants while you call. Do not delay departure to search every corner of the room. A missing battery is important information even when you cannot prove it was swallowed.

An undamaged casing does not settle the risk
Pet Poison Helpline’s clinical explanation notes that some button batteries can cause tissue injury through an electrical current. Damaged batteries can also release irritating chemicals, and swallowed batteries may obstruct the digestive tract. The veterinary team decides which examination or imaging is appropriate.
Ulcers may not be apparent immediately. Do not use a comfortable-looking mouth, an animal accepting a treat or a few symptom-free minutes as a reason to cancel the call.
Do not improvise a kitchen treatment
Ask the professional what, if anything, to do before arrival. Do not give peroxide, salt, an improvised neutralizing mixture or a large meal to push the object through. Instructions about rinsing or oral intake must account for the animal’s ability to swallow and the exposure involved; follow the advice you are given.
This article is not an at-home treatment protocol. Veterinary poison consultations may have a fee. Keep the instructions and any case reference available to the receiving clinic rather than making several disconnected calls without sharing the earlier advice.
Look beyond spare batteries afterward
Once urgent care is arranged, include battery-powered cards, toys, hearing aids and remote controls in the household storage check. Secure used batteries as carefully as new ones. A closed device can still become accessible when chewed.
Our food-stealing management article addresses a different everyday behavior. Battery access needs physical prevention and an emergency response, not a training test with the real object.
