Why paint thinner is hazardous

The solvent is rapidly absorbed, depressing the central nervous system and damaging the stomach lining.

A few millilitres can cause seizures, drooling and a characteristic sweet‑like odor on the breath.

Spills are often invisible on concrete, and pets may lick the residue from their paws after playing on a fresh‑painted floor.

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 paint-thinner-ingestion poisoning

  • Sudden drooling and foaming within 10‑20minutes
  • Rapid, shallow breathing or gasping for air
  • Tremors or seizures developing in the first half hour
  • Vomiting that may be bloody after 30‑60minutes
  • Unsteady gait that progresses to collapse or coma

What to do right now

  1. Call your vet or the Merck Veterinary Manual hotline immediately
  2. Do not induce vomiting because of the high aspiration risk with a hydrocarbon solvent
  3. Keep the pet warm and limit movement to prevent worsening CNS depression
  4. Bring the original paint‑thinner container or a sample of the liquid for identification
  5. Transport to an emergency veterinary clinic for oxygen therapy and supportive care
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
