Can Dogs Eat Cashews? Here's Everything You Need to Know
Getting more cashews in our diet is certainly a great idea for humans, but can our canine companions enjoy them as well? Unlike macadamia nuts, cashews aren’t toxic to dogs and are safe for consumption. However, there are some basic guidelines you should keep in mind before you introduce these tropical nuts to your pet’s diet.
This article will tell you everything you need to know about giving cashews to dogs and what to look out for in order to avoid any health issues.
Quick Answer: Can Dogs Eat Cashews?
Yes—dogs can eat plain, unsalted, shelled cashews in small amounts, but they should only be an occasional treat because cashews are high in fat and calories.
- Dogs can safely eat cashews, as long as they are shelled, unsalted, and not mixed with other nuts.
- Even though these nuts are not the best treat option, feeding them occasionally and in small amounts shouldn’t cause harm.
- The safe amount depends on your dog's size—typically 1-2 cashews for small dogs, 2-3 for medium dogs, and 3-5 for large dogs, given only as an occasional treat.
- Avoid salted, flavored, or chocolate-covered cashews, and never give your dog mixed nuts due to the risk of toxic varieties like macadamia nuts.
- Cashew butter and cashew milk are only safe in very small amounts if they contain no xylitol, excess sugar, salt, or other harmful additives.
- If you have more questions about feeding cashews to your dog, consult your vet.
How Many Cashews Can Dogs Eat?
The safe amount depends on your dog's size, weight, and overall health. Here's a general guideline:
Dog Size | Maximum Amount | Frequency |
|---|---|---|
Small dogs (under 20 lbs) | 1-2 cashews | Occasional treat only |
Medium dogs (20-50 lbs) | 2-3 cashews | Occasional treat only |
Large dogs (over 50 lbs) | 3-5 cashews | Occasional treat only |
Important note: Final portions depend on your dog's individual calorie needs, health history, and current diet. Always consult your veterinarian before introducing new treats, especially if your dog has existing health conditions.
Safety Checklist
Before giving your dog cashews, make sure they meet these requirements:
- Plain and unsalted only – No added salt, seasonings, or flavorings
- No shells, chocolate, or mixed nuts – Shells contain toxins; chocolate and some nuts (like macadamias) are dangerous to dogs
- Avoid if your dog has certain health conditions – Dogs with pancreatitis, obesity, diabetes, or those on prescription diets should not have cashews unless your vet approves
When to Call Your Vet
Contact your veterinarian immediately if:
- Your dog ate a large amount of cashews
- The cashews were salted, flavored, chocolate-covered, or mixed with other nuts
- Your dog shows symptoms like vomiting, diarrhea, lethargy, abdominal pain, or weakness
Pro tip: Knowing which toxic foods to avoid is the first step in making sure that your furry friend is safe. Finding the right pet insurance plan for when they get sick can cover up to 90% of the costs, taking the pressure off you and allowing you to focus on your pet getting better.
Can dogs eat cashews?
Cashew nuts provide nutrients that are beneficial to your canine companion. They contain omega-6 fatty acids, which in the correct balance with omega-3 fatty acids, help control inflammation in the body and keep the coat soft and shiny.
Cashews also contain antioxidants, fiber, protein, as well as a number of vitamins and minerals, including vitamin K, flavanols, calcium, copper, magnesium, iron, manganese, phosphorus, and zinc.

However, while dogs can safely eat a couple of cashews, consuming them in large amounts can lead to a number of health issues down the road.
- Obesity. Most pups can safely eat cashew nuts from time to time. However, cashews contain high levels of fat, so pet parents need to keep this in mind when giving them as a treat. A dog weighing 10 lbs requires around 220 calories per day, and considering that an ounce of these nuts contains about 160 calories, it will account for almost 75% of their daily needs. Too many cashews can lead to obesity which, in turn, can put your dog at risk of serious health problems. Generally speaking, treats should not make up more than 10% of your pup’s daily caloric intake.
- Pancreatitis. The high-fat content in cashews is also a concern when it comes to dogs prone to pancreatitis. Too much fat in the diet can cause the pancreas to become inflamed because it is unable to break down the fat. Some of the most common symptoms of the disease are decreased appetite, abdominal pain, and lethargy. If not diagnosed on time, pancreatitis can require aggressive treatment.
- Stomach upset. Fatty meals are difficult to digest, so too many cashews can cause stomach upset, diarrhea, and vomiting. That’s why you should ensure that they’re out of your pup’s reach when you can't supervise them.
- Bladder stones. The phosphorus in cashew nuts can harden inside your pup’s bladder, contributing to the formation of bladder stones.
If your four-legged friend is on a prescription diet for other medical problems (kidney disease, bladder stones, diabetes, etc.), it’s best to consult your vet before giving your pet cashews.
Can cashews cause an allergic reaction?
While nut allergies can be quite dangerous in humans, they are not so common in canines. Most often, dogs are allergic to foods like dairy, eggs, or chicken.
However, even though the chances of your pet developing an allergic reaction to cashew nuts are low, pet owners should know the symptoms of an allergic reaction (itching, swelling, and hives) when giving their pooches any human food for the first time.
Because some kinds of nuts can be quite toxic to dogs, it is important that you don’t give your pet cashew nuts out of a variety pack. Cases of allergic reactions to nuts in humans prove that it takes a very small amount to cause problems.
If you believe your dog is having an allergic reaction, stop feeding them cashews and call your vet.
Pro tip: Dog insurance can help cover the cost of allergy testing and treatment, in addition to helping you afford veterinary care for a number of other pet health issues.
How to feed cashews to dogs
You should be careful that there aren’t any other types of nuts in the package. Some nuts can be very dangerous for dogs. For instance, macadamia nuts are very toxic to them. Toxicity signs include weakness, vomiting, depression, difficulty walking, and cold intolerance. Other kinds of nuts that are bad for pups include walnuts, black walnuts (also known as hickory nuts), almonds, and pecans.

In addition, inspect nuts for mold before feeding them to your dog. Some types of mold can contain aflatoxin, which can upset your pet's stomach, cause bowel obstruction, or even liver failure.
Always choose a packaged and unsalted variety (raw or roasted). Salted cashews should especially be avoided in dogs with heart disease.
Avoid unshelled cashews. The shells contain a toxin called anacardic acid, which can cause gastroenteritis and irritate the skin.
Never feed your pup any kind of chocolate-covered nuts, as well as any nut products sweetened with xylitol. Both chocolate and xylitol are toxic to dogs and can result in serious illness.
Can dogs eat cashew butter and cashew milk?
Can dogs eat raw cashews?
Yes, dogs can eat raw cashews, but only if they are plain, unsalted, and shelled. Raw cashews should be given sparingly due to their high fat content. Always ensure they are free from mold and other contaminants.
Can dogs eat roasted cashews?
Yes, dogs can eat roasted cashews as long as they are plain and unsalted. Avoid any roasted cashews with added oils, salt, seasonings, or flavorings. Roasted cashews should still be given in small amounts as an occasional treat.
Can dogs eat salted cashews?
No, dogs should not eat salted cashews. The high sodium content can lead to excessive thirst, urination, and in severe cases, sodium ion poisoning. This is especially dangerous for dogs with heart disease or kidney problems.
Can dogs eat cashew butter?
Dogs can eat cashew butter in very small amounts, but only if it contains no xylitol, chocolate, excess sugar, salt, or added flavorings. Many store-bought cashew butters contain additional ingredients that are unsafe for dogs. A tiny amount (no more than half a teaspoon for small dogs or one teaspoon for larger dogs) can be given occasionally. Always check the ingredient label carefully before offering cashew butter to your dog.
Can dogs drink cashew milk?
Dogs can drink cashew milk only if it is plain and unsweetened, and only in small amounts. Many commercial cashew milk products contain added sugars, sweeteners (including xylitol), flavorings, or other additives that can be harmful to dogs.
Always read the label carefully. Even plain cashew milk should be given sparingly due to its fat content.
Can puppies eat cashews?
Puppies can technically eat plain, unsalted cashews, but extra caution is needed. Puppies have smaller bodies and developing digestive systems, making them more sensitive to high-fat foods.
The fat load from even one or two cashews can be significant for a small puppy. It's best to avoid giving cashews to puppies and stick to puppy-appropriate treats instead.
My dog ate one cashew—what should I do?
If your dog ate one plain, unsalted cashew, there is typically no cause for concern. Monitor your dog for any signs of stomach upset, such as vomiting, diarrhea, or lethargy.
However, if the cashew was chocolate-covered or part of a mixed nut package, contact your veterinarian for advice. Also call your vet if your dog ate multiple cashews or shows any concerning symptoms.
Can dogs eat mixed nuts?
No, dogs should not eat mixed nuts. Mixed nut packages often contain macadamia nuts, which are highly toxic to dogs, as well as other nuts that may be salted, flavored, or otherwise unsafe.
Even if the package appears to contain only "safe" nuts, the risk of cross-contamination or misidentification makes mixed nuts too dangerous for dogs.
Healthy alternatives to cashews for dogs
Even though giving your canine companion cashews once in a while is okay, there are many healthy treat alternatives that are just as tasty:
- Carrots are one of the favorite treats among pups looking for new tastes. Besides being sweet, they are also very nutritious.
- Peaches and bananas are packed with vitamins, but they also contain high sugar content,t and for that reason, should be served in moderation.
- For a hydration boost during hot summer days, consider feeding your pup some juicy watermelon. Just be sure the seeds and rind are removed before serving.
- Homemade dog biscuits made with whole wheat flour, eggs, peanut butter, and canned pumpkin are an excellent way to please your pup’s sweet cravings risk-free.
Key Takeaways
- Dogs can safely eat cashews, as long as they are shelled, unsalted, and not mixed with other nuts.
- Even though these nuts may not be the best treat option, feeding them occasionally and in small amounts won’t cause any harm.
- If you have more questions about feeding cashews to your dog, consult your vet.
