What should I do if my dog ate raisins, currants and sultanas?

  1. Call your vet or a pet poison line now.
  2. Note what was eaten, roughly how much, and when.
  3. Go to the vet right away, even if your dog seems fine.
  4. Move your dog away from any remaining food.

Don't

  • Don't make your dog vomit unless a vet tells you to.
  • Don't wait for signs; kidney failure can develop days later.

Symptoms to watch for

  • Vomiting
  • Diarrhea
  • Belly pain
  • Low energy
  • Loss of appetite
  • Blood in stool
  • Excessive thirst and urination

When signs appear: Some dogs get sick within a few hours; kidney failure can develop over 1-3 days

Why

Raisins are dried grapes and carry the same unexplained kidney toxin, possibly tartaric acid. Baked goods, bagels and trail mix can hide them.
