🫘 Nuts & Seeds

Can dogs eat pistachios?

In moderation
Pistachios are not toxic, but it is best to avoid feeding them to dogs.

Why

Pistachios are not poisonous, but they are high in fat and salt, which can lead to gastrointestinal upset and pancreatitis, especially in larger quantities. The nuts and shells are a choking hazard, and pistachios can carry urushiol, which causes an allergy-like reaction, and aflatoxin, a mold toxin that can make dogs lethargic and cause seizures. For these reasons veterinarians recommend keeping pistachios away from dogs.

How much is safe

Best avoided; if a dog gets one or two plain, unsalted, shelled pistachios it is unlikely to be harmful, but they should not be offered regularly.

Warning signs to watch for

Diarrhea, vomiting, loss of appetite, and lethargy; potential pancreatitis from the high fat content.
