Yes, you can feed dogs walnuts in small amounts, but there are important safety rules you need to follow.
Walnuts aren’t toxic to dogs the way grapes or macadamia nuts are, so a plain, unsalted walnut here and there usually won’t harm your pup.
That said, “can you feed dogs walnuts” isn’t a simple yes across the board, because the type of walnut and how it’s prepared matters a lot.
In this post, we’ll walk through whether you can feed dogs walnuts safely, the risks to watch for, and how to do it the right way.
Can You Feed Dogs Walnuts? The Short Answer
You can feed dogs walnuts, but only plain, unsalted ones and only in moderation.
Here’s why that distinction matters so much:
1. Plain Walnuts Are Non-Toxic to Dogs
The English walnuts you buy in the baking aisle are not toxic to dogs.
They contain healthy fats, a bit of protein, and some omega-3 fatty acids that can actually support your dog’s skin and coat.
So if you’re wondering “can you feed dogs walnuts,” the answer is yes when they’re plain and given as an occasional treat.
2. The Real Danger Is Mold and Molds
The biggest risk with walnuts isn’t the nut itself, it’s mold.
Walnuts that have been stored poorly or left on the ground can grow mold that produces tremorgenic mycotoxins.
These toxins can cause tremors, vomiting, and even seizures in dogs.
That’s why you should never let your dog eat walnuts you find outside or ones that look old, discolored, or smell musty.
3. Salt and Seasoning Are a No-Go
Salted, roasted, or flavored walnuts are bad news for dogs.
Too much salt can lead to dehydration, sodium ion poisoning, and in serious cases, seizures.
Some flavored walnuts also contain garlic or onion powder, both of which are toxic to dogs.
So when you feed dogs walnuts, always stick to the plain, unsalted kind.
4. Black Walnuts Are a Different Story
Black walnuts, the wild ones with the hard shells, are more problematic.
They’re more likely to carry mold, and the shells and hulls can be tough on a dog’s digestive system.
If you have black walnut trees in your yard, keep your dog away from fallen nuts.
How to Feed Dogs Walnuts Safely
If you want to feed dogs walnuts, a little planning goes a long way.
Here’s how to do it right:
1. Stick to One or Two Nuts Max
Walnuts are calorie-dense and high in fat.
For a small dog, even one walnut can be a lot.
A good rule of thumb is one or two plain walnuts for a medium to large dog, and just a tiny piece for a small breed.
Treats should never make up more than about 10% of your dog’s daily calories.
2. Chop Them Up to Prevent Choking
Whole walnuts can be a choking hazard, especially for small dogs.
Break them into small pieces so your dog can chew safely.
This also helps prevent them from swallowing a big chunk that could get stuck.
3. Watch for Tummy Trouble
Some dogs have sensitive stomachs and don’t handle rich, fatty foods well.
Too many walnuts can cause vomiting, diarrhea, or even pancreatitis in extreme cases.
The first time you feed dogs walnuts, give just a tiny piece and watch how they react.
4. Skip Walnuts If Your Dog Has Health Issues
If your dog is overweight, has pancreatitis, or struggles with fat digestion, skip the walnuts entirely.
The high fat content can trigger flare-ups in dogs with these conditions.
When in doubt, ask your vet before you feed dogs walnuts.
What About Other Nuts?
If you’re already thinking about nuts, it helps to know where walnuts fit compared to others.
1. Safe Nuts in Moderation
Plain peanuts, cashews, and almonds can be okay in tiny amounts for many dogs.
The same general rules apply: unsalted, unseasoned, and small portions only.
2. Nuts to Avoid Entirely
Macadamia nuts are toxic to dogs and can cause weakness, tremors, and vomiting.
You should also avoid any nut that’s coated in chocolate, sugar, or xylitol, which is highly toxic.
So while you can feed dogs walnuts, not every nut is safe.
So, Can You Feed Dogs Walnuts?
You can feed dogs walnuts, but only plain, unsalted ones in small amounts.
Always check for mold, avoid black walnuts, and skip the salted or flavored varieties.
Keep portions tiny, chop them up, and watch your dog for any bad reaction.
If your dog has health issues or you’re just unsure, check with your vet first.
Treat walnuts as an occasional snack, not a regular part of your dog’s diet.
That way, you get to enjoy sharing a little something with your best friend, safely and without worry.
