Can dogs eat pistachios?
No, it is best to avoid them. Pistachios are not toxic in themselves, but they are fatty and usually salty, can upset the stomach or lead to pancreatitis, and nuts or shells can cause choking. They can also grow harmful mould.

Why
Pistachios are high in fat and salt, which can cause stomach problems, and fatty, salty snacks can lead to pancreatitis. Even shelled nuts can be a choking hazard. Mould on nut shells can produce aflatoxin, which can make dogs weak and lethargic, upset the stomach and even cause seizures.
Signs to watch for
- Vomiting or diarrhoea
- Belly pain, nausea or low energy (possible pancreatitis)
- Weakness and tiredness
- Choking
What to do
If your dog ate a few pistachios, watch for vomiting, diarrhoea or belly pain. Call your vet if your dog ate a lot of them or their shells, seems to be choking, or shows weakness, tiredness or any of these signs.
