Walnuts are not considered toxic in dogs unless the actual shell of a walnut is ingested or the walnuts are moldy. These nuts do, however, contain a large amount of fats and oils which in some dogs can result in gastrointestinal upset such as vomiting and diarrhea, and in some cases pancreatitis. I would monitor your dog closely for these symptoms and seek veterinary care if they occur. You can read more about GI upset at http://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=353. Best of luck to you and Libby!!!
