Can Dogs Eat Pistachios? Benefits and Risks of Pistachios

Properly processed pistachios are not toxic to dogs, but there are several reasons why feeding pistachio nuts to your dog is not ideal. Like most tree nuts, pistachios can contain aflatoxin, a compound made by aspergillus mold. If eaten in large quantities, aflatoxin can wreak havoc on your dog’s digestive system. In addition, pistachio nuts contain urushiol—a compound present in poison ivy. Urushiol causes an allergic reaction in dogs. Pistachios also contain high levels of salt and fat, which can be detrimental to your dog’s health. Lastly, the hard outer shell of the pistachio poses a choking hazard to your pooch.

Pistachios contain antioxidants, vitamins, and minerals that can be beneficial to humans and dogs. They are a good source of potassium, iron, and calcium. They’re also high in vitamin K, E, and B6. They are high-fiber nuts that contain fatty acids and proteins. While all these things are beneficial to your dog’s health, the risks of feeding your dog pistachios outweigh the possible rewards.

Though it may be safe for your dog to have a couple of shelled pistachios, large quantities of pistachios pose serious health risks to your dog. Here are some of the risks associated with feeding your dog pistachios:

1. 1. High fat content. Pistachios, like macadamia nuts and cashews, have a high fat content. Too much fat in your dog’s diet can cause pancreatitis (inflammation of the pancreas). Pancreatitis symptoms include abdominal pain, loss of appetite, upset stomach, vomiting, diarrhea, dehydration, and lethargy. In addition, too much fat can contribute to obesity.
2. 2. High sodium content. Salted and flavored pistachios contain high levels of sodium and other seasonings. An excess of salt in your dog’s diet can cause vomiting, diarrhea, and lethargy. It can also cause excessive thirst which can lead to increased urination.
3. 3. High phosphorus content. Too much phosphorus in your dog’s diet can lead to the formation of bladder stones.
4. 4. Choking hazard. Pistachio shells can cause blockage in your dog’s esophagus. If your dog eats pistachios and has a hard time breathing or swallowing, they may require an X-ray to assess the damage to their esophagus.
5. 5. Intestinal obstruction. In addition to being a choking hazard, pistachio shells can get lodged in your dog’s digestive tract causing gastrointestinal distress. This too may require an X-ray and physical examination by a veterinarian.
6. 6. Harmful compounds. Urushiol is a compound found in poison ivy and causes an allergic reaction in dogs around their mouth and face. Pistachios also contain aflatoxins, a compound made by aspergillus mold—a type of mold present in many agricultural products—that can cause pistachio poisoning.

Pistachios contain aflatoxins, a compound made by aspergillus mold. Aspergillus mold is commonly found on agricultural crops, such as peanuts, cottonseed, corn, and tree nuts. If your dog eats a large number of pistachios, they may experience aflatoxin poisoning. Symptoms include loss of appetite, vomiting, jaundice, and liver failure.

Certain human foods can cause adverse reactions in canines, so always consult your veterinarian to determine whether it is safe to add these foods to your pet’s diet. This article is for educational and informational purposes and is not a substitute for medical or dietary advice.
