Safety guide

Is Pistachios safe for dogs?

Use with caution

Not toxic, but not recommended — high fat, usually heavily salted, and the shells are a choking and blockage risk.

Pistachios aren't poisonous to dogs, but they're a poor choice. They're very high in fat, which can trigger stomach upset or, with regular access, pancreatitis. They're also typically sold heavily salted, and the hard shells are a genuine choking and intestinal-obstruction hazard. Pistachios can also carry Aspergillus mould, which produces aflatoxin — harmful to the liver. A single stolen nut is unlikely to cause serious harm, but pistachios shouldn't be offered as a treat. If your dog has eaten several, or any shells, keep an eye on them.

Symptoms to watch for

  • Vomiting or diarrhoea
  • Loss of appetite or lethargy
  • Abdominal pain or a hunched posture (possible pancreatitis)
  • Gagging, retching or straining to pass stool (possible shell obstruction)

What to do immediately

  1. 1Remove any remaining pistachios and shells out of reach
  2. 2Note how many were eaten and whether shells were swallowed
  3. 3Offer fresh water and withhold further food while you monitor
  4. 4Watch closely for the next 24-48 hours

When to call your vet

Your dog ate a large quantity, swallowed shells, or shows repeated vomiting, diarrhoea, belly pain or lethargy — these can signal pancreatitis or a blockage.
