Can Dogs Eat Pistachio Nuts? Everything You Need To Know

Yes, dogs can eat pistachio nuts in moderation. Pistachios aren’t toxic to dogs by themselves, but it is vital to check the quality and the serving methods before feeding them to your canines. Additionally, pistachio nuts may be difficult for dogs to digest and assimilate the nutrients completely. Hence, avoid feeding these nuts to dogs with sensitive stomachs.

What are Pistachio Nuts? 

Pistachio is a crunchy oblong-shaped nut belonging to the cashew nut family. They are the oldest flowering nut trees in the world, which produce seeds enclosed within a rigid exterior shell. These shells must be broken open to access the nuts for consumption. They are native to Central Asia and the Middle East. Their history of consumption can be traced back to Bronze age Central Asia and was referred to in the inscriptions from the Roman and Byzantine empires. Also, it’s believed that pistachios were cultivated in the “Hanging gardens of Babylon,” which is one of the world’s seven wonders.

Pistachio nuts are expensive as they are cultivated only in a few countries worldwide. However, they can live up to 300 years and are well-known for their high proteins, almost equivalent to an egg. Alternatively, these nuts are known as ‘happy nuts’ in China and ‘Smiling nuts’ in Iran.

Why are Pistachio Nuts Bad for Dogs? 

Pistachios are detrimental to your dog’s health if consumed in larger quantities for the following reasons. They include: 

1.High-Fat Content

Pistachios are known for their high-fat content. Fats should make up about 25%-30% of your dog’s total caloric intake. Anything more than this could mean a higher-fat diet. A higher fat diet can tax your dog’s liver as they work hard to digest the fatty contents. Therefore, sustained high-fat levels cause obesity and lead to pancreatitis. 


Inflammation of the pancreas disturbs the secretion of digestive enzymes and insulin production. This disturbance causes fluctuation in the blood sugar levels, which may lead to a life-threatening condition in your canine.

  • Vomiting 
  • Abdominal pain 
  • Diarrhea 
  • Lethargy
  • Dehydration

If left untreated, sodium poisoning can lead to tremors, seizures, and kidney damage.

  • Straining to urinate
  • Abdominal pain
  • Frequent urination, but only urinating a small amount each time
  • Urinating in odd places and inside the house
