Safety guide
Is Pistachios safe for dogs?
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
- 1Remove any remaining pistachios and shells out of reach
- 2Note how many were eaten and whether shells were swallowed
- 3Offer fresh water and withhold further food while you monitor
- 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.
