Can Dogs Eat Pistachios?

AVOID

AVOID — pistachios are not toxic to dogs, but shells, salt, fat and possible mould make them a nut we would skip.

We recommend not feeding pistachios. Shells and whole nuts can cause choking or a blockage, pistachios are often sold salted, the nuts are high in fat, and they can carry mould toxins even when no mould is visible. A few plain nuts are unlikely to harm a healthy dog.

If your dog has already eaten pistachios, contact your veterinarian or an animal poison control service straight away — even if your dog seems fine.

The full answer

PetMD and the American Kennel Club both describe pistachios as not toxic to dogs. Both still advise against feeding them.

Pistachio shells, and the nuts themselves, can be a choking hazard. PetMD notes that pistachios with or without shells can cause an intestinal blockage.

Pistachios are high in fat and are often sold salted. Fatty, salty snacks can cause stomach upset and may trigger pancreatitis.

Pistachios can carry aflatoxins, toxins made by mould, even when the nuts look normal. The Merck Veterinary Manual reports serious aflatoxin poisoning in dogs. This is most relevant to large amounts or spoiled nuts, not a single nut.

Pistachio ice cream and desserts are different products and are not assessed here.

Risks and Things to Know

  • Shells and whole nuts can cause choking or a blockage.
  • Salted pistachios add sodium.
  • High fat can cause stomach upset and may trigger pancreatitis.
  • Mould toxins (aflatoxins) can be present without visible mould.

How Much Can Dogs Eat?

We recommend not offering pistachios as a treat.

Put discarded shells in a bin your dog cannot open.

How Should I Prepare It?

  • Pistachios have no recommended preparation for dogs.
  • If you want to share a treat, choose one from our list of dog-friendly foods instead.

What If My Dog Ate Too Much?

If a healthy dog ate a few shelled pistachios and is acting normally, watch for stomach upset.

Contact a vet if your dog ate a large amount, swallowed shells, or shows vomiting, diarrhoea, belly pain, straining or loss of appetite.

Contact a vet straight away if the nuts were old or mouldy, or if you notice yellowing of the gums or eyes, weakness or unexplained bruising.

Nuts & Seeds

Almonds

Almonds are not toxic to dogs in the way macadamia nuts or grapes are. The reasons to skip them are practical: whole nuts can choke or block, the fat can upset digestion, and most almond products are salted, coated or flavoured.

AVOID

Nuts & Seeds

Walnuts

Plain English walnuts are not automatically highly toxic, yet fat, choking, shells, mould and the more concerning black walnut add up. We recommend keeping walnuts away from dogs.

Nuts & Seeds

Pecans

We recommend not feeding pecans. They are high in fat, whole nuts and shells can cause choking or a blockage, and mouldy pecans can contain toxins that cause tremors and seizures. A single dropped, fresh pecan is unlikely to harm a healthy dog.

Salt

Do not add salt to treats or table scraps for your dog. If you know your dog ate only a small bite of an ordinary salted food, that is different from eating loose salt, salt dough or de-icing salt, or drinking seawater.

Ice Cream

Three separate things matter: lactose, fat and sugar, and particular ingredients such as xylitol or chocolate that are genuinely toxic to dogs.
