Call a vet now

Call your vet or the nearest emergency vet right now. Windshield wiper fluid is toxic to dogs and can cause kidney failure, low blood pressure, and incoordination.

What to do right now

  1. Call your vet or the nearest emergency vet.
  2. Note what, how much, and when your dog ate.
  3. Bring the packaging.
  4. Keep your dog calm.

Don't

  • Do not make your dog vomit unless a vet tells you to.

Why it can be dangerous

Windshield wiper fluids most often contain a moderate to high concentration of methanol.[1] They may also contain low-concentration isopropanol and additional antifreezes, including ethylene glycol or propylene glycol.[1]

Signs to watch for

  • Low blood pressure
  • Incoordination
If your pet is struggling to breathe, has collapsed, is having a seizure or can't stand up: go to the nearest vet now.
