It sounds like Zeus has vomiting and diarrhea. Walnuts are toxic to dogs and can cause an obstruction as well as GI upset. Plus they are fatty, and can cause pancreatitis. Same with pistachios. He could have any of those diseases from what he ate, and when a dog isn't eating, is vomiting, and having diarrhea, he cannot be treated at home. Your only option is to take him into a vet immediately.
