Are Walnuts Bad for Dogs? Are Walnuts Toxic to Dogs?

The simple answer is, they can be!

Walnuts are highly nutritious nuts and have far more, healthier omega-3 fats, than most other nuts.

They are high in antioxidants and are believed to improve brain health, lower cholesterol and prevent heart disease in humans.

However, this does not automatically mean that they are a healthy treat for your pooch.

Walnuts can often be infected with fungi, which can cause your dog serious problems. These problems can include vomiting, tremors, and even seizures.

Fungi in Walnuts

These types of nuts have a high moisture content, because of this, they can be infected with fungi at any stage of the growing process. It doesn’t matter if they are shelled or unshelled. Even a drying process prior to eating will not stop fungal growth. 

Some say, washing walnuts with vinegar or boiling water and then drying thoroughly will remove any fungal growth. However, this seems a lot of hassle and is not guaranteed to remove all or any of the fungi.

Some of these fungi produce Tremorgenic Mycotoxins which is a toxic compound that is harmful to dogs.

Black Walnuts

As well as fungi, Black walnuts or Eastern American Black walnuts contain juglone which is a toxin that causes dogs to get an upset gastric intestinal. Otherwise known as an upset stomach. Walnuts can also cause intestinal blockages.

English Walnuts

English walnuts can also contain fungi, cause an upset stomach, and can create an intestinal obstruction in canines.

Japanese Walnuts

Again, as with black and English walnuts, Japanese walnuts can cause stomach pain and intestinal blockage. If your dog eats Japanese walnuts, these also contain fungi which again, can cause vomiting but also tremors and seizures.

Can dogs eat pistachios?

Pistachios are my personal favorite. But it is not recommended that you should ever give them to your dog. Like walnuts, they pose a risk of choking and obstruction of their intestine.

Conclusion

Can dogs eat walnuts? No, walnuts are bad for dogs. Most nuts, if not toxic, are still high in fat, which can cause discomfort and even stomach ache for dogs. But toxic nuts like walnuts can cause far more severe symptoms and complications.

Based on my research, I would highly recommend avoiding giving nuts to dogs. If you want to give your pup a treat, there are plenty of other options available for our dogs that are far safer and healthier for them.  

The only nut treat I would give my dog would be a small amount of peanut butter specifically made for dogs, placed inside a dog toy, like a Kong, or even spread on a slow dispensing lick pad.
