Can dogs eat walnuts? No, dogs should not eat walnuts. While English walnuts (the most common store-bought type) might cause only mild digestive upset, black walnuts and moldy walnuts can cause serious poisoning, and even plain walnuts can trigger pancreatitis due to their high fat content. Walnuts can be a choking hazard and cause intestinal blockages, especially in small dogs.

Which Types of Walnuts Are Most Dangerous?
- Black walnuts (Juglans nigra): Extremely toxic, can cause vomiting, diarrhea, tremors, and seizures due to the toxin juglone.
- Moldy walnuts: May contain tremorgenic mycotoxins that cause rapid neurological symptoms.
- Seasoned/salted walnuts: Extra sodium or additives like garlic or onion powder are toxic to dogs.
- English walnuts (store-bought): Not acutely toxic but cause GI upset or pancreatitis in moderate to large quantities.
Are Walnuts Safe for Dogs to Eat?
While not all walnuts are equally toxic, the risks far outweigh any benefits. Even “safe” store-bought walnuts can become contaminated with mold or cause gastrointestinal issues, especially if consumed in excess. Dogs prone to pancreatitis, or small breeds, are at higher risk.
Should I Make My Dog Throw Up After Eating Walnuts?
Never induce vomiting without your vet’s specific instruction. Forcing vomiting in a dog already showing severe symptoms (tremors, confusion, or weakness) can be dangerous. Always consult with your veterinarian immediately.
Are Walnuts Bad for Dogs?
Yes—walnuts are high in fat, easily contaminated with toxic mold, and often a choking or blockage hazard for small dogs. Pancreatitis (inflammation of the pancreas) is a common and potentially life-threatening reaction to fatty foods, including walnuts.
Can Dogs Die From Eating Walnuts?
Death is possible, especially if a dog eats black walnuts, moldy nuts, or large amounts that cause pancreatitis, blockage, or toxic reactions. Rapid treatment increases the chances of recovery.

Alternatives to Walnuts for Dogs
There are safer treat options for your dog, such as peanuts (unsalted), small amounts of roasted cashews, or certified dog treats. Always avoid seasoned, salted, or chocolate-covered nuts.
Conclusion: Play It Safe—Skip Walnuts, Choose Better Treats!
Walnuts bring more risks than benefits for dogs. Between potential toxins, high fat content, and risk of choking or obstruction, they are simply not worth the gamble. If your dog accidentally eats walnuts, especially black, wild, or moldy ones, contact a veterinarian immediately.
For healthy and tasty treats, try dog-friendly fruits like apples or blueberries, and keep all nuts well out of reach.
