Can Dogs Eat Walnuts

It is hard to remember what should be fed to the dog and what should be avoided. Walnuts have a high-fat content. They are not advisable to be fed. Walnuts are healthy for dogs if they are fresh and fed in moderation.

Walnuts have some nutritional value but the fungi in walnuts are harmful to dogs. In the research they find out walnuts in grocery stores are infected with some fungi. Walnuts can be contaminated with fungi of any kind whether they are shelled or not.

Walnuts Toxic Content

Walnuts are high in nutritional value. They are rich in fatty acids, vitamins, and antioxidants. But this does not necessarily mean you should give it to your dog.

Walnuts are high in moisture content they are dried for eating but it doesn’t remove the fungal growth. Walnuts can be contaminated at any level from harvesting to the shop shelf.

The reason walnuts are not suitable for a dog to eat. They contain fungi that grow toxic content responsible for cancer, tremors, and seizures.


It is a poisonous compound that is naturally produced in food items such as dry fruits, nuts, and spices due to some fungi. They are known to be carcinogenic ( likely to cause cancer ). Moreover, they can cause tremors and seizures.

If your dog eats a moldy walnut, the doctor will treat him with activated charcoal. Activated charcoal absorbs mycotoxins.

What if Dog Ate a Walnut

There is no problem if your dog ate one or two walnuts. But you should be concerned if he ate out of the garbage or ate a lot of walnuts. Keep an eye on your dog and take him to the vet if you observe any unusual behavior.

Side effects of eating Moldy Walnut

If your dog ate a walnut that is not fresh he will start vomiting. He might have some digestive issues as well before other severe symptoms. Even a small number of mycotoxin causes tremors but they are so fine to be observed.

In severe poison, tremors grow stronger and can get worse. But there is a great chance your dog can recover if he eats walnuts with a mycotoxin.

Can Dogs Eat Cooked Walnuts

It is true that cooking kills bacteria and makes food safe to eat. But, not in the case of walnuts. Cooking does not kill mycotoxins at all because they are not living organisms. Mycotoxins are chemical by-products in Walnuts.

Can Dogs Eat Walnuts if Washed

Visible fungi on walnuts are removed by washing. Some people suggest to wash them in the vinegar solution or boil them. Yet, the fungus does not only settle on the top layer but also it does grow deep below the surface.

So washing walnut cannot guarantee it is all clean to be eaten by a dog. A mycotoxin is a microscopic substance hence there is no way to tell if they are washed off.

Nutritional Value of Walnuts

Other than toxic content walnut is rich in vitamins, antioxidants, and fats. Consuming fresh walnuts in moderation is not harmful at all. It does contain some healthy benefits:

  • Antioxidants make walnuts very nutritious.
  • Walnuts promote healthy sleep as it contains melatonin.
  • Moreover, it contains Omega-3. It is an important nutrient for dogs.
  • Vitamins are beneficial for dogs’ health.
  • Walnuts are good for lowering cholesterol.
  • It improves mental health as well.

If a dog eats an ounce of walnuts, a dog will be fed with many nutrients and fats. An ounce contains about 18 g of fats in walnuts. Whereas on average a dog needs 14g – 21 g of fat per day. But, an ounce will not be enough to provide the required calories and proteins.

It is correct to say dogs are designed to get most of the nutritional value from fats. But there are other replacements as well.

The bottom line is the risk of mycotoxin is not worth it. Walnut itself is not bad for dogs but fungi with them are poisonous for them.

Moderation is the key to feed a dog. Consult a vet before changing the diet plan of your dog.
