Household bleach is one of the most common cleaning chemicals found in homes and a frequent cause of pet poisoning. Sodium hypochlorite, the active ingredient in chlorine bleach, is corrosive and can burn the mouth, esophagus, and stomach if swallowed. Pets may also be exposed by walking through freshly cleaned floors and licking their paws, inhaling irritating fumes, or chewing through a bleach bottle.
Dogs and cats are attracted to the strong smell of bleach, and some cats may even rub against treated surfaces. Symptoms of exposure include excessive drooling, vomiting, pawing at the mouth, coughing, wheezing, red or irritated skin, lethargy, and refusal to eat. Inhalation of bleach fumes can cause respiratory distress, while eye contact may lead to pain and corneal damage.
Prevention is the safest approach. Keep all bleach and bleach-containing products in secure cabinets or high shelves where pets cannot reach them. Use pet-safe alternatives such as enzymatic cleaners or diluted vinegar solutions whenever possible. If you must use bleach, dilute it properly, ventilate the area, and keep pets completely out of the room until all surfaces are dry and the odor has cleared.
If you suspect your pet has ingested or inhaled bleach, do not wait for symptoms to worsen. Do not induce vomiting, as this can cause additional burns. Rinse affected areas with water and contact your veterinarian or a pet poison control center immediately.
