Can Dogs Eat Pistachios? Guide for Pet Owners

Oct 31, 2023 | Dogs & Puppies | 4 comments

When sharing our favorite snacks with our four-legged companions, we must exercise caution and ensure that the foods we offer them are safe for their consumption. Pistachios, those delightful green nuts, often raise questions among dog owners. Can dogs eat pistachios?

The short answer is that while pistachios aren’t highly toxic to dogs, they come with potential risks that every dog owner should know.

Are Pistachios Bad for Dogs? Risks of Feeding Them to Your Dog

When it comes to the health of your furry companion, it’s essential to understand the potential risks associated with feeding them certain foods. While pistachios might seem like a harmless snack, there are several reasons why they might not be the best choice for your dog. Here’s a detailed look at the risks involved:

  • High-Fat Content: Pistachios are relatively high in fat, which can be problematic for dogs. A diet that’s too rich in fatty foods can lead to pancreatitis—a painful inflammation of the pancreas. Pancreatitis can cause symptoms like abdominal pain, vomiting, and loss of appetite; severe cases can be life-threatening.
  • Sodium Concerns: Many store pistachios are salted, and excessive salt consumption can harm dogs. Ingesting too much salt can lead to sodium ion poisoning, which causes symptoms ranging from increased thirst and urination to vomiting, diarrhea, tremors, seizures, and even death in severe cases.
  • Aflatoxin Risk: Aflatoxins are harmful compounds produced by certain molds that can grow on nuts, including pistachios. Ingesting aflatoxins can negatively affect a dog’s health, including liver damage. Dogs are more sensitive to aflatoxins than humans, making this a concern.
  • Choking Hazard: The shells of pistachios can pose a choking hazard to dogs. In addition, eating whole pistachios, shells, and all can lead to digestive issues, as the shells are not easily digestible and can cause blockages in the digestive tract.
  • Allergic Reactions: Like humans, dogs can develop allergies to certain foods. While pistachio allergies are relatively rare, they can still occur, leading to symptoms like itching, skin rashes, and gastrointestinal distress.

In a nutshell (pun intended), while a small amount of plain, unsalted pistachio without the shell might not immediately harm a healthy dog, the risks associated with pistachios outweigh the potential benefits.

How Many Pistachios Can Your Dog Eat?

If you’re considering sharing a pistachio or two with your furry friend, it’s essential to understand that moderation is vital. While pistachios are not highly toxic to dogs, they still come with potential risks, as discussed earlier. Here’s a closer look at how many pistachios your dog can safely consume:

  • Size Matters: The size of your dog plays a significant role in determining how many pistachios they can safely eat. A giant dog can tolerate a few more pistachios than a smaller dog.
  • Occasional Treat: Pistachios should only be an occasional treat for your dog. They should never become a regular part of their diet. A good rule is that treats should not make up more than 10% of your dog’s daily caloric intake.
  • Plain and Unsalted: If you share a pistachio with your dog, ensure it’s plain and unsalted. Salted pistachios can lead to sodium ion poisoning, which can have serious health consequences.

While a small, occasional nibble of a plain, unsalted pistachio might not pose an immediate danger to a healthy dog, it’s best to play it safe and avoid offering them pistachios altogether.

Can Dogs Eat Pistachio Shells?

It’s important to remember that pistachio shells are unsuitable for canine consumption. While dogs might be tempted to chew on them due to their texture and scent, pistachio shells can pose several risks to your furry friend’s health:

  • Choking Hazard
  • Digestive Issues
  • Intestinal Blockages
  • Dental Problems

Given these potential risks, preventing your dog from chewing or ingesting pistachio shells is strongly recommended. If you suspect your dog has ingested pistachio shells or any other foreign objects, it’s advisable to consult with your veterinarian for guidance.

What to Do If Your Dog Eats Pistachios

Consuming a significant amount of pistachios can lead to severe illness in dogs. Hence, it’s strongly advised to prevent your dog from accessing pistachios. Dogs can be curious and might only sometimes discern what’s safe to eat.

If your dog gets into your pistachios or discarded pistachio shells, it’s best to consult with your dog’s veterinarian or your closest emergency veterinary clinic immediately.

Professional guidance can make a crucial difference in ensuring your dog’s health and preventing potential complications. Immediate action can help ensure your dog’s well-being.


Pistachios are not highly toxic to dogs but come with risks that make them an unsuitable snack for your furry friend. The high fat content, potential salt and mold issues, and the risk of pancreatitis or sodium ion poisoning make pistachios a treat to avoid sharing with your dog. Your dog’s health and well-being should always be a top priority, so opt for safe and vet-approved treats instead.
