Never mix bleach and ammonia. When combined, these common household cleaners react to form chloramine gas, a toxic irritant that can severely damage the lungs and airways of dogs and cats. Because pets are close to the floor and have sensitive respiratory systems, they can be harmed by fumes even in small, poorly ventilated spaces.
Exposure usually happens when a pet breathes in chloramine gas from a recently cleaned area, licks a contaminated surface, or walks through spilled cleaner and later grooms its paws. Inhalation can cause coughing, wheezing, difficulty breathing, and chemical pneumonia; direct contact can burn the eyes, skin, mouth, and esophagus.
Prevention is straightforward: use only one cleaner at a time, read labels carefully, and never mix chlorine bleach with ammonia or acidic products. Keep pets out of rooms being cleaned until surfaces are thoroughly rinsed and the area is fully aired out. Store all cleaning chemicals securely in a locked cabinet.
If you suspect your pet has been exposed, get them into fresh air immediately and contact your veterinarian or an emergency clinic. Quick action can be critical
