Why dryer sheets are toxic
The sheet releases quaternary ammonium compounds that irritate the gastrointestinal lining.
When the pet chews the soft fabric, the chemicals can also be inhaled, causing coughing or laboured breathing.
They are often left on the floor after a laundry load, looking like a small white rectangle that pets mistake for a treat.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of dryer-sheet-ingestion poisoning
- Vomiting within 1‑3hours of ingestion
- Excessive drooling or foaming at the mouth
- Coughing or laboured breathing shortly after eating the sheet
- Diarrhoea that may be watery or contain mucus
- Lethargy or reluctance to move as irritation worsens
What to do right now
- Call your vet or the Pet Poison Helpline right away
- Do not induce vomiting because the chemicals can be aspirated into the lungs
- Rinse the pet’s mouth with water and keep it upright to reduce aspiration risk
- Gather any remaining sheet fragments to show the veterinarian
- Take the pet to an emergency clinic for monitoring and supportive care
