Antifreeze puddles and dogs: what to do

Extremely toxic. Even a tiny amount of antifreeze can cause fatal kidney failure; dogs need treatment within 8-12 hours.

If your dog ate or touched this, call your vet or a pet poison line now

Find an emergency vet

What to do now

  1. Call your vet or a pet poison line now.
  2. Go to a vet even if your dog seems fine; it may seem to recover before the kidneys fail.
  3. Bring the product container, if there is one, so the vet can check the ingredients.

Don't

  • Don't wait for signs; treatment works best early.

Signs to watch for

  • Wobbly, drunk-like walking
  • Drooling
  • Vomiting
  • Extreme thirst and peeing more
  • Seeming to get better, then getting worse
  • Severe lethargy
  • Seizures or coma
  • Kidney failure

When signs appear: 30 minutes to 12 hours; kidney failure follows in 36-72 hours

Why

Most antifreeze contains ethylene glycol, which has a sweet taste that attracts dogs. It can cause kidney failure, and treatment works only if started early.
