Mothballs might be great at taking out pests like cloth moths and silverfish, but they can be seriously dangerous for our dogs. In this video, I answer the big question—are mothballs toxic to dogs?—and I break down why they’re risky in the first place. Mothballs aren’t just repellents; they’re pesticides that release toxic vapors as they slowly turn from a solid into a gas, which is why they’re meant for sealed containers (not open rooms where pets can be exposed). I also cover how little it can take to cause a problem. According to the American Veterinary Medical Association, a single mothball can poison a dog, and certain types can be even worse. I go over common symptoms like mothball-scented breath, lethargy, panting, pale gums, tremors or seizures, diarrhea, and vomiting (sometimes with blood), plus the tricky part—signs can show up within hours or be delayed for days. Most importantly, I explain what to do if your dog gets into mothballs: treat it like a life-threatening emergency, call your vet or a pet poison helpline, and get to an animal hospital fast if symptoms are severe. There’s no antidote, so treatment focuses on decontamination and supportive care—things like inducing vomiting (when appropriate), activated charcoal, bloodwork, and even transfusions if anemia becomes severe.
