Cold-Weather Caution — Keep Hand Warmers Away from Pets

Know Hand Warmer Dangers for Pets

As colder Wisconsin days settle in, hand warmers become a go-to for those of us seeking a quick way to keep our fingers toasty. But while they’re handy for humans, these little heat packs can pose serious risks to pets. Knowing the dangers can help you keep your furry friends safe from an accidental encounter with hand warmers.

Why Hand Warmers Can Be Harmful to Pets

Hand warmers contain ingredients like iron powder, activated carbon, vermiculite, and salt, all of which can be dangerous if ingested by pets. While the outer layer might seem harmless, a pet’s curiosity — especially if it’s triggered by a novel smell or texture — can lead to licking, chewing, and, ultimately, swallowing bits or even the entirety of a hand warmer.

Most hand warmers are small enough to seem like an innocuous toy, making them easy to overlook. But if left within a pet's reach, they can quickly go from a cozy convenience to a health hazard.

What Happens if a Pet Ingests a Hand Warmer

When pets ingest hand warmers, their bodies can react to the toxic ingredients in multiple ways, depending on the type of warmer and how much they’ve consumed. Here’s what you need to know.

  • Iron toxicity — Iron, commonly found in hand warmers, can cause gastrointestinal upset and toxicity. Symptoms of iron poisoning include vomiting, diarrhea, lethargy, and abdominal pain. High levels of iron can damage the liver and cause severe health complications, leading to organ failure if left untreated.
  • Sodium poisoning — Salt in hand warmers can also lead to toxicity in pets, especially small dogs and cats. High salt intake can cause dehydration, vomiting, diarrhea, and even seizures.
  • Choking and obstruction — Ingesting the entire hand warmer could pose a choking risk or cause an obstruction in the digestive tract. Pets with an obstruction may show signs like loss of appetite, vomiting, and lethargy. Immediate veterinary care is essential to prevent a dangerous blockage.

Signs Your Pet May Have Eaten a Hand Warmer

Pets who have ingested a hand warmer may show signs fairly quickly. Symptoms can include:

  • Vomiting or dry heaving
  • Diarrhea
  • Loss of appetite
  • Weakness and lethargy
  • Rapid or shallow breathing
  • Uncoordinated movements

if you suspect your pet has eaten a hand warmer or find any remnants of one nearby, keep an eye on them. Don’t wait for symptoms to escalate — getting ahead of the situation could save your pet from serious harm.

What to Do If Your Pet Eats a Hand Warmer

If you suspect or know that your pet has ingested a hand warmer, here’s what you should do:

Contact your veterinarian immediately. Call your veterinarian or an emergency animal hospital for advice. Be ready to describe the type of hand warmer your pet ingested, as well as any symptoms they’re exhibiting. Time is critical, so reach out as soon as you notice a problem.

Do not induce vomiting. Trying to make your pet vomit without professional guidance can be dangerous, especially with certain toxic substances. Always consult a vet before taking this step.

Monitor symptoms closely. If your vet advises watching your pet at home, observe for worsening symptoms like vomiting, lethargy, or unsteadiness. Keep your pet calm, and ensure they have access to fresh water.

Prepare for a vet visit. If advised, take your pet to the clinic promptly. Bring along any packaging or remaining parts of the hand warmer, as this can help the veterinarian determine the best course of action.

An Ounce of Prevention

To prevent future incidents, consider a few simple precautions to keep hand warmers out of your pet’s reach:

  • Store unused hand warmers securely — Keep hand warmers in a drawer, cupboard, or another place your pet can’t access.
  • Dispose of used hand warmers carefully — After using a hand warmer, place it in a trash can with a secure lid. Some hand warmers may still contain toxic ingredients even after they’ve cooled down.
  • Be vigilant in outdoor activities — If you use hand warmers on hikes or outdoor outings with your pet, make sure they’re safely stored or disposed of when no longer needed.

 Hand warmers may be a welcome relief on a chilly day, but they can spell danger for pets who come into contact with them. Understanding these risks and knowing what to do if your pet ingests one can make a dramatic difference in an emergency. By taking precautions and acting quickly if an incident occurs, you’ll help ensure that the only warmth you’re sharing is that which comes from snuggling with your furry friend.
