Frequently Asked Questions
Are pistachios toxic to dogs like macadamia nuts?
Pistachios are not acutely toxic in the same way as macadamia nuts, but they carry significant risks from aflatoxin mold, high fat content, and choking from shells. They’re best avoided entirely.
What is aflatoxin and why does it concern pistachios?
Aflatoxin is a toxic compound produced by Aspergillus mold that commonly grows on pistachios. It can cause liver damage and long-term organ issues. Dogs are more sensitive to aflatoxin than humans.
My dog ate several shelled pistachios — should I worry?
If they were unsalted, the immediate risk is low. Watch for vomiting, diarrhea, or lethargy over the next 48 hours. Call your vet if symptoms develop.
