Why your dog should avoid eating nuts

While some nuts are safe in small amounts, others can be very toxic to dogs when eaten. We’ve listed some common nuts that are often found in pantries, and what the effect on your dog could be if they eat them.

Peanuts are safe for dogs in small quantities. They should be raw or roasted, unsalted, and without their shells. Peanut butter used as a treat should be natural and only include peanuts without the addition of sugars, salts, or artificial sweeteners. If they eat too many peanuts, this could lead to pancreatic issues.  


These can be difficult to digest and can cause stomach and gastric intestinal upset. Watch out for flavoured almonds as these can be irresistible to dogs.

Macadamia nuts

Macadamia nuts are commonly listed as one of the top human foods to avoid feeding your dog. They contain an unknown toxin that can lead to neurological issues and are very high in fat, which can put your dog at risk of gastrointestinal problems or lead to pancreatitis.

Walnuts and pecans

Pecans and walnuts are very similar and may contain a toxin that can cause seizures or neurological symptoms. They can also cause gastric intestinal upset or obstruction.  


Pistachios, although not toxic to dogs, are another variety of nut which are rich in fat and can lead to upset stomach or pancreatitis. An occasional pistachio, without the shell, won’t do any harm, but there are much safer, healthier treats available.

Brazil nuts

Like almonds, Brazil nuts are not toxic to dogs, but are high in fat and not easily digested. A dog that eats Brazil nuts may experience an upset stomach.


Cooked or roasted cashews are generally safe in moderation, but because of their fat content, they can cause an upset stomach.


Hazelnuts are not toxic to dogs and are generally safe to feed in moderation. However, because of their size and shape, they can pose a choking or obstruction risk to smaller dogs.

While some nuts are safe in small quantities, there are plenty of other treats out there that are much healthier for your dog.
