Can dogs eat pecans?

Caution — mould risk

Pecans aren't acutely toxic like macadamias, but they can carry moulds (aflatoxins) that cause tremors and seizures. Plus the usual high-fat pancreatitis risk.

The full picture

Pecans are in the same family as walnuts and share similar risks: not acutely toxic like macadamias, but prone to carrying moulds that produce tremorgenic mycotoxins. These moulds can trigger muscle tremors, seizures, and neurological symptoms. Pecans are also high in fat (pancreatitis risk), and the shells can cause intestinal blockage. Salted, chocolate-covered, or spiced pecans (common at Christmas) have extra problems. A single plain pecan accidentally dropped is unlikely to harm a medium dog, but pecans shouldn't be a deliberate share — especially not pecan pie, which also contains corn syrup and sometimes raisins.

If your dog has eaten pecans

Monitor for tremors, vomiting, or lethargy. Call your vet if your dog ate more than one or two, or if pecan pie was involved (contains other problematic ingredients).
