Can dogs eat walnuts?

No.

Walnuts aren't a safe treat for dogs. Black walnuts and moldy walnuts (including ones fallen from trees) can contain toxins that cause tremors and seizures. Even plain store-bought walnuts are fatty and can cause blockages.

Did your dog just eat walnuts?

If your dog ate black walnuts, moldy walnuts, or walnuts from the ground, call your vet or a pet poison line now. Tremors can start within hours.

Call your vet, an emergency vet, or a 24/7 pet poison line:

US numbers. A consultation fee may apply. Don't try to make your dog vomit unless a vet tells you to.

Why walnuts are dangerous

  • Moldy walnuts can contain toxins such as penitrem A, which cause tremors, seizures, and vomiting
  • Black walnuts are especially risky, and fallen walnuts in yards often grow mold
  • All walnuts are high in fat, which can lead to pancreatitis
  • Whole walnuts and shells can cause choking or a blockage, especially in small dogs

Signs to watch for

  • Vomiting or diarrhea
  • Shaking, tremors, or twitching
  • Wobbliness or seizures (an emergency)
  • Belly pain, weakness, or not eating

Walnut trees in the yard

If you have a walnut tree, pick up fallen nuts and husks regularly, especially in autumn, and don't let your dog chew them. Moldy husks are a common cause of poisoning.

Frequently asked questions

My dog ate one walnut from the bag. Is that OK?

One fresh, plain, store-bought walnut is unlikely to cause harm. Call your vet if it was moldy, a black walnut, from the ground, or if your dog shows any shaking or vomiting.

Are walnut shells dangerous?

Yes. Shells are hard and sharp, can cause blockages, and old shells and husks may carry mold.
