Can dogs eat pistachios?

Caution — not toxic but problematic

Pistachios aren't toxic but they're high in fat, often very salty, and the shells are a choking hazard. Not a good treat.

The full picture

Pistachios sit in the same awkward 'not toxic but not good' zone as almonds. They're high in fat (pancreatitis risk), usually heavily salted, and can harbour the same Aspergillus mould as walnuts and pecans — though less commonly. The shells are genuinely dangerous: a dog that eats a whole pistachio (shell included) can develop intestinal blockages. If your dog steals a shelled, unsalted pistachio it's unlikely to cause an emergency, but don't share pistachios deliberately.

Risks to watch for

  • High fat causes pancreatitis
  • Shells cause blockage/choking
  • Salt in most commercial pistachios
  • Mould toxins possible
