Can Dogs Eat Pecans?

AVOID

AVOID — plain pecans are not a classic dog poison, but their fat, hard shells and risk of mould make them a nut we would skip.

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.

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

The full answer

PetMD describes pecans as not toxic to dogs, but advises against feeding them. Veterinary sources do not agree on every detail, so we do not describe plain pecans as poisonous. The practical concerns are clear enough for us to recommend avoiding them.

Pecans are very high in fat. Too many can cause vomiting and diarrhoea, and fatty food can trigger pancreatitis, a painful condition that can become serious.

Pecans in their shells, and hard shell pieces, can be a choking hazard and may cause a blockage in the digestive tract.

Mouldy pecans are the more urgent concern. Mould on nuts can produce toxins that affect the nervous system. The Merck Veterinary Manual describes vomiting, drooling, wobbliness, tremors and seizures in dogs, starting within one to two hours or several hours after eating mouldy food.

Pecan pie, candied pecans and praline are different products with sugar, butter and other ingredients, and are not assessed on this page.

Risks and Things to Know

  • High fat can cause stomach upset and may trigger pancreatitis.
  • Whole nuts and shells can cause choking or a blockage.
  • Mouldy or fallen nuts can contain toxins that cause tremors and seizures.
  • Pecan pie and candied pecans add sugar and fat.

How Much Can Dogs Eat?

We recommend not offering pecans as a treat.

If you have a pecan tree, keep your dog away from fallen nuts.

How Should I Prepare It?

  • Pecans 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 one or two fresh, plain pecans and is acting normally, watch for stomach upset.

Contact a vet if your dog ate several pecans, swallowed shells or whole nuts, or has a condition affected by fat, such as a history of pancreatitis.

Contact a vet straight away if the pecans may have been mouldy or old, or if you see tremors, wobbliness, drooling or seizures.

This guide is for general educational purposes and isn't a substitute for advice from your veterinarian. If your dog has eaten something potentially toxic or is showing concerning symptoms, contact a veterinarian promptly.

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.

Macadamia Nuts

Macadamia nuts are one of the few foods with a well-described, dog-specific toxic syndrome. Affected dogs typically show weakness, wobbliness, vomiting and sometimes a raised temperature. Most recover with veterinary care, but no amount is an appropriate treat.

Nuts & Seeds

Pistachios

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.

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.
