Can Dogs Eat Walnuts?

Alright, dog parents, let’s talk nuts – walnuts, to be more specific. Wondering if your fur baby can snag a bite without landing you both at the vet? 

Well, while walnuts are nutrient-rich for us, it’s a different story for our four-legged friends. So, let’s tread carefully.

Navigating the walnut world for your dog can feel like a sudoku puzzle in expert mode! Some types are like ticking time bombs that could seriously mess with your dog’s health. But other store-bought, unsalted walnuts can be fine, if used correctly. Let’s guide you through! 

And you might even ask whether, with many healthier, belly-rub-inducing snacks out there, it is worth sharing walnuts with your beloved pooch? Why risk it when you could just give them a good old doggie biscuit? 

Walnuts and Dogs

Meet the black walnut and the English walnut – two distinct types, much like cats and dogs themselves. 

Knowing who’s who in the walnut family is essential, especially when your fur friend’s health could be in the balance.

Types of Walnuts

Black walnuts are your typical tough nuts with a hard shell and stand-out flavor native to good old North America! They could be toxic to your dog, leading to an upset stomach or even scary seizures.

Then there’s the milder type, the English walnut. They may have softer shells and gentler taste, but they’re not the “good guys” by default. 

While these walnuts are technically safe for dogs to eat, they may still present some risks and are not considered the optimal treat for your furry friend.

Healthy Snacks Versus Health Risks

While we may enjoy a handful of walnuts as a tasty, nutritious snack, for our furry pals it’s really a bit of a tightrope walk. 

Sure, a few unsalted walnuts from your local store might not ring the ‘puppy-danger-alert,’ but it is important to monitor your pet for any adverse reactions.

So be sure to watch out for potential pitfalls: Allergies, for starters, since dogs and nuts aren’t always best buddies. Those hard shells? They’re a choking risk and could damage your pup’s digestive tract. Plus, beware of mold and the nasty aflatoxin, which is bad news for both dogs and humans.

Weighing the nutty risks, you might therefore just decide it’s just not worth it. 

Well, indeed! Why not swap that walnut for a carrot, blueberries, or some dog-safe peanut butter? Now that’s a recipe for wagging tails and canine smiles!

Toxicity of Walnuts for Dogs

Now, not all walnuts are canine troublemakers, but black walnuts and moldy ones could pose a real threat to your furry friends.

Black walnuts contain a toxic chemical called juglone, a real no-go for dogs. Moldy walnuts? Even worse. They can harbor dangerous fungi-borne mycotoxins that are not just carcinogenic but can also mess with your dog’s nervous system.

Signs and Symptoms of Harm

If your furry friend goes on a covert walnut raid, you’ll want to be on the lookout for several symptoms that could indicate walnut toxicity.

Vomiting and diarrhea may manifest quickly, as these are the body’s natural ways of expelling harmful substances. 

Tremors and seizures, likely triggered by tremorgenic mycotoxins, are also warning signs. You may notice a concerning decrease in energy, with your typically lively buddy becoming weak and lethargic. 

Abdominal pain could also be evident, with your dog showing discomfort and tenderness in the belly area due to gastrointestinal distress. 

Lastly, a higher-than-normal body temperature, or hyperthermia, could signal that your dog’s system is in distress and in need of immediate attention.

When to Seek Veterinary Help

If your dog displays any of the signs mentioned above after consuming walnuts, it is crucial to seek veterinary assistance immediately.

Early help could save your fur pal from severe pain and prevent possible serious issues like long-term neurological damage.

A quick reaction to the toxin trouble can turn the tide in your doggy’s favor. So remember, when it comes to walnut toxicity, it’s all about staying vigilant and acting immediately.

Other Health Concerns Related to Dogs Eating Walnuts

Digestive System Impact 

Walnuts come packing high-fat content. If your fur buddy sneaks a snack, it might cause an upset stomach, vomiting, or even life-threatening pancreatitis. 

Plus, if your pooch gobbles up a fair few nuts or their shells, they could bring on a big old blockage in your dog’s intestines. Nasty stuff. 

Choking Risk

Imagine this: your fur pal sniffs a whole walnut or its shell, nosedives into it, and ends up choking. This is a plausible scenario, so take care to avoid this happening.

Whether it’s a fun bounce-around toy or a sneaky snack, keep whole walnuts out of your dog’s reach.

Obesity and Weight Gain

Remember the high-fat aspect too. If your pooch gets “nutty” about walnuts, they could pile on quite a few extra pounds.

Those extra pounds could spell bad news. Think diabetes, joint problems, and heart disease. 

Safe Consumption of Walnuts by Dogs

You may be wondering, can dogs ever really safely snack on a walnut or two? Well, technically, your furry friend can enjoy a couple of store-bought, unsalted walnuts.

However, remember the key word here: technically. It’s not exactly the canine cuisine recommended by dog diet gurus. But if you’re thinking about serving up some walnuts to your fur pal, here are some tips to keep in mind.

Avoid salted or coated walnuts

Avoid walnuts salted or coated with artificial flavors, chocolate coatings, or any other ‘added extras.’ Salted walnuts can increase the sodium content in your dog’s diet, which is not healthy.

Limit walnut quantity

While a small number of walnuts might be okay for your dog, consuming large amounts can lead to health issues. Keep the serving size to a minimum to avoid any potential problems.

Cooked vs. raw walnuts

Cooked walnuts, particularly those without added ingredients, are generally safer than raw walnuts for dogs. However, the best option is to stick to dog-specific treats whenever possible.

Monitor cholesterol

Turns out, dogs and grandpas have something in common: keeping track of cholesterol matters to them! Walnuts are rich in cholesterol, and too many can lead to weight gain and other health issues.

In conclusion, although some walnuts may not pose significant risks to your dog’s health, it’s better to stick to pet-specific treats and be cautious about giving them nuts in general. 

And remember, when in doubt, your best bet is to check with a vet for personalized advice about your dog’s diet.

Alternatives to Walnuts for Dogs

Before you toss your fur buddy that walnut, remember there’s a whole universe of healthier, yummier alternatives that your pooch will drool over. Here, we break down some dog-friendly treats for your buddy.


Not poison for pooches but more of a ‘sometimes’ snack. Make them unsalted and go for sugar-free, xylitol-free peanut butter. It’s like a taste adventure for your dog, only less risky!


Not a canine hazard, but the choking potential can be a concern. Opt for simple, unsalted almonds and keep it to a nibble-sized serving.


Yes, in small numbers. Again, unsalted is the way to go, and make them a rare treat!


These are okay in limited doses, but keep an eye on that fat content – pancreatitis isn’t a walk in the park. Say yes to unseasoned, and say no to salted pecans.


Not deadly to dogs, but let’s be honest, that high-fat content isn’t what we’re aiming for. So let’s keep these to a sometimes-treat for your pal.

Dog treats

The best for last! Skip the nutty worry and go straight for dog-specific munchies tailored for your fur buddy’s nutrition. A ton of awesome options await, from tailor-made meat bites to veggie sticks and everything in between.

Being a responsible dog parent means balancing treats and health. While it’s tempting to share your snacks, it’s safer to stick with dog-specific treats. They’re formulated for your pet’s well-being, so you can keep those tails wagging while also keeping your furry friend healthy.

Some nuts are really bad news for dogs. Macadamia nuts are particularly dangerous and can cause symptoms like weakness, vomiting, and tremors. 

Almonds can also be harmful, as they can lead to upset stomachs and potential blockages in the gastrointestinal tract. In general, it’s best to keep nuts away from dogs as many can harm their health.
