How to Serve Pistachios Safely

Keep pistachios and discarded shells inaccessible. Avoid salted, chili-lime, garlic, chocolate-coated, dessert, and mixed-nut products. Choose a plain dog-safe treat rather than trying to make pistachios safe by portioning them.

What to Watch For

Watch for vomiting, diarrhea, loss of appetite, belly pain, lethargy, coughing or gagging after a shell, weakness, tremors, or seizures. Moldy shells and large fatty exposures are more concerning than a single plain nut.

  • Assuming non-toxic means suitable as a routine dog treat.
