Dogs can eat cashews and walnuts, but only in small amounts and only under safe conditions.
So if you’ve been wondering, “can dogs eat cashews and walnuts?” the short answer is yes, these nuts aren’t toxic to dogs.
That said, “can dogs eat cashews and walnuts” comes with some serious caveats because plain cashews and walnuts are totally different from the seasoned, salted, or chocolate-covered versions sitting in your pantry.
In this post, we’ll break down whether dogs can eat cashews and walnuts, why moderation matters so much, and how to serve these nuts safely.
Let’s get into it.
Why Dogs Can Eat Cashews and Walnuts
Dogs can eat cashews and walnuts, and here’s why:
1. Plain Cashews Are Non-Toxic to Dogs
Cashews aren’t on the ASPCA’s list of toxic foods for dogs.
This means dogs can eat cashews without any of the poisoning risks that come with things like grapes or macadamia nuts.
The key word here is plain.
Raw or unsalted cashews with zero seasoning are the only ones safe for your pup.
Chocolate-covered, honey-roasted, or salted cashews are a hard no.
2. Plain Walnuts Are Also Safe
Dogs can eat walnuts too, as long as they’re plain English walnuts with no shell and no salt.
Walnuts aren’t toxic to dogs either, so they can be given as an occasional treat.
But there’s a big catch here.
Black walnuts and moldy walnuts can contain tremorgenic mycotoxins, which are dangerous for dogs.
So when you ask, “can dogs eat cashews and walnuts?” understand that plain English walnuts are fine while moldy ones are not.
3. These Nuts Offer Some Nutritional Value
Can dogs eat cashews and walnuts and actually benefit from them?
Yes, in moderation.
Cashews bring healthy fats, magnesium, and a bit of plant-based protein to the table.
Walnuts are famous for their omega-3 fatty acids, which can support your dog’s skin and coat.
The keyword in that last sentence is “a bit” because nuts are far from a nutritional staple for dogs.
They’re treats, not meals.
Why Moderation Matters When Dogs Eat Cashews and Walnuts
Even though dogs can eat cashews and walnuts, going overboard causes real problems.
1. Nuts Are Packed With Fat
Cashews and walnuts are both high in fat.
Too much fat in a dog’s diet can trigger pancreatitis, a painful and sometimes serious inflammation of the pancreas.
This is why a couple of small nuts is a treat, and a handful is a vet bill.
2. Cashews Are Calorie Dense
Cashews contain roughly 160 calories per ounce.
For a 20-pound dog, that’s a big chunk of their daily calorie allowance.
If you keep feeding cashews without measuring, weight gain creeps in fast.
And dogs that eat cashews regularly need their other meals adjusted to compensate.
3. Choking and Blockage Risks Are Real
Whole nuts can be a choking hazard, especially for small dogs.
Walnut shells are the bigger danger.
Shells can splinter and cause intestinal blockages that may require surgery.
If you’re going to let your dog eat cashews and walnuts, always remove shells, chop the nuts into small pieces, and supervise closely.
4. Salt and Seasoning Can Be Toxic
Salted nuts can lead to sodium poisoning in dogs.
Signs include excessive thirst, vomiting, and tremors.
And when it comes to asking “can dogs eat cashews and walnuts,” seasoned or flavored versions should never be the ones you feed.
Stick to raw or plain roasted, with nothing added.
How to Feed Cashews and Walnuts to Your Dog Safely
Wondering how to actually serve these nuts?
Here’s the safe approach:
1. Keep Portions Tiny
A good rule of thumb is one or two small nuts for a medium dog, less for toy breeds.
For large dogs, three or four is plenty.
Keep nuts under 10 percent of your dog’s daily calories.
2. Prepare Them Properly
Always remove shells, chop the nuts into small pieces, and skip any that show signs of mold.
Plain is the rule, so no salt, sugar, chocolate, or xylitol-sweetened coatings.
3. Ask Your Vet First
If your dog has a history of pancreatitis, is overweight, or has allergies, check with your vet before feeding any nuts.
Some dogs simply shouldn’t eat cashews or walnuts at all.
So, Can Dogs Eat Cashews and Walnuts?
Dogs can eat cashews and walnuts in small, plain, unseasoned portions, as long as shells are removed and portions stay tiny.
Nuts aren’t toxic to dogs, but their high fat content, choking risks, and calorie density mean they should stay an occasional treat rather than a regular snack.
Now that you know where things stand on “can dogs eat cashews and walnuts,” you can share a safe bite or two with your furry friend without worrying.
