Dogs should not have pecans. Pecans contain a toxin called juglone, which is harmful to dogs, and they are also prone to a mold that contains aflatoxins, which can cause serious health issues. In addition to their toxicity, pecans are very high in fat, which can trigger pancreatitis in dogs. Eating pecans may cause vomiting, diarrhea, tremors, seizures, and other symptoms. Even a small amount, especially if moldy, can be dangerous, so it is best to avoid giving pecans to dogs and consult a veterinarian if a dog ingests them.
