Your Dog Could Be Burning Your House Down And You Don’t Even Know It

We all know dogs are trouble when left alone. Chewed shoes, knocked over trash cans, maybe a couch cushion or two destroyed. But what if I told you your furry best friend could actually start a fire while you're gone? Yeah, a real fire. It happened to a family in Chapel Hill, North Carolina, and they watched the whole thing go down on their home security camera.

So How Does This Even Happen?

The culprit here? Lithium-ion batteries. Those are the same batteries powering your phone, your earbuds, your remote, basically everything in your house. When a dog chomps down on one of these devices, it can puncture the battery or cause internal damage that triggers what's called thermal runaway, basically an uncontrolled chain reaction of heat that leads to fire or explosion. Fire investigator Richard Meier, who has investigated over 700 fires, put it simply: it gets hotter and hotter, and it can't stop itself.

What Devices Should You Worry About?

Well, pretty much anything with a battery. The list includes cellphones, remote controls, smartwatches, earbuds, fitness trackers, flashlights, and even rechargeable vape devices. Meier also pointed out that the mouse on his own computer has a lithium-ion battery, so yeah, nothing is off limits for a determined pup. The bigger the battery, the bigger the potential fire, but even small ones can ignite nearby rugs, curtains, or bedding.

It's Not Just Dogs Either

Before you go blaming man's best friend for everything, cats are just as guilty. Meier says he once had a cat that constantly chewed on electrical cords and somehow survived. Between 2020 and 2024, electrical failures caused more than 46,000 annual home structure fires in the US, and pets chewing on wires are a real part of that problem. So whatever pet you have, this is definitely worth paying attention to.

What Can You Actually Do About It?

The fix is pretty simple: pick up your stuff. Don't leave devices on the couch or the floor where your pet can get to them. Meier also says don't charge your phone or laptop on the bed or couch as that is a fire risk even without a pet involved. And if you're throwing away anything with a battery in it, don't just toss it in the trash. Lithium batteries need to go to a proper recycling facility because they cause hundreds of fires at waste facilities every year. A few small habit changes could literally save you and your house.
