Can dogs have walnuts?

Not all nuts are bad for the health of your dogs. You can still feed them with some nuts (such as cashew nuts) in small quantities. However, walnuts (particularly black walnuts) are not recommended for your dogs. Excessive consumption of walnuts by dogs can be toxic which poses serious health risks.

Walnuts are very high in fat and can cause dietary problems. The usual symptoms include vomiting and diarrhea. On a more serious level, walnuts can result in the development of other serious conditions such as gastroenteritis or pancreatitis. Walnuts also get mouldy very easily, which makes it unsafe for consumption.

Are dogs allergic to walnuts?

Like other foods, your dog could also be allergic to walnuts. 

Are black walnuts bad for dogs?

Black walnuts are one of the most common walnuts. Black walnuts contain juglone (An allelopathic aromatic compound found in the leaves, roots, husks, and bark of plants in the Juglandaceae family). Juglone is a poisonous substance that can cause seizures or convulsions in dogs, which explains why black walnuts are so toxic to dogs.

If your dog accidentally consumes black walnuts, some of the symptoms you should watch out for include tremors, vomiting, and seizures.
