My dog ate pistachios. What should I do?
A small amount is unlikely to cause serious harm in a healthy dog. Remove any remaining food, offer fresh water and watch for vomiting, diarrhea, a painful belly or lethargy over the next 24-48 hours. Call your vet if your dog ate a large amount, is small, young or has health problems (such as pancreatitis), or if the food contained onion, garlic, chocolate or xylitol.

Pistachios and dogs: FAQ
Can dogs have pistachios?
It is best not to give dogs pistachios. They are not considered toxic, but shells can cause choking or blockage, they are high in fat, and pistachios can carry aflatoxin-producing mold.
My dog ate pistachio shells. What should I do?
Watch for vomiting, constipation, belly pain or loss of appetite, and call your vet, especially for small dogs.
Is pistachio ice cream okay for dogs?
No. It is high in sugar and fat, and dairy can upset the stomach.
What nuts are safe for dogs?
Plain peanuts and cashews are the safest in small amounts. Avoid macadamia nuts (toxic) and moldy or black walnuts.
Can puppies eat pistachios?
No. Puppies are smaller and more vulnerable than adults, so it is best avoided entirely.
