Can dogs eat peanuts? Yes. Plain, unsalted peanuts, shelled and either dry-roasted or raw, are safe for most dogs in small numbers. Peanuts aren’t actually nuts but legumes, and unlike macadamias they aren’t toxic. The issues are fat, salt, flavor coatings and shells. Here’s how many to give, which kinds to skip, and how peanuts compare with true nuts.
Yes, in moderation. Share a few plain, unsalted, shelled peanuts. Skip salted, honey-roasted, chocolate-coated and spicy peanuts, and never give shells. Each peanut has about 6 calories and half a gram of fat, so they add up fast.

Are Peanuts Good for Dogs?
They bring protein, healthy fats, niacin and vitamin E, which is why dogs go wild for them. Still, the American Kennel Club recommends only plain, dry-roasted or raw unsalted peanuts, and only a few. They’re calorie-dense, so they’re best as high-value rewards rather than handfuls.
Which Peanuts Are Safe? Salted, Roasted, Boiled
| Peanut type | Verdict | Why |
|---|---|---|
| Dry-roasted, unsalted | Best choice | No added salt or oil |
| Raw, shelled | Okay from a trusted source | Raw peanuts can carry aflatoxin mold |
| Boiled, unsalted | Okay | Soft; most boiled peanuts are heavily salted |
| Salted | A stolen one or two is fine | Too much salt causes thirst and worse |
| Honey-roasted, chocolate, spicy | Avoid | Sugar, chocolate, chili, garlic or onion seasoning |
| In the shell | Avoid | Shells can choke dogs or block the gut |
About aflatoxin: PetMD explains that raw peanuts grown in hot, humid conditions can develop this mold toxin, which can damage the liver. Human-grade peanuts from a reputable brand keep the risk low. Never feed peanuts that look shriveled, discolored or moldy.
Peanuts vs. Other Nuts: What’s Safe?
| Nut | Verdict | Main concern |
|---|---|---|
| Peanuts | Safe, plain, a few | Fat, salt, shells |
| Cashews | A few, plain | Fat |
| Almonds | Not recommended | Hard to digest, choking |
| Pecans, walnuts | Avoid | Mold toxins, blockage; see pecans |
| Macadamia nuts | Toxic | Weakness, tremors; see macadamia nuts |
How Many Peanuts Can a Dog Eat?
A widely used guideline from the WSAVA keeps treats under about a tenth of daily calories. Because peanuts are fatty, we’d stay well below that:
| Dog’s weight | Suggested peanuts | Approx. calories | Approx. fat |
|---|---|---|---|
| 10 lb (4.5 kg) | 1 to 2 | ~6-12 kcal | ~0.5-1 g |
| 25 lb (11 kg) | 3 to 4 | ~18-24 kcal | ~1.5-2 g |
| 50 lb (23 kg) | 5 to 6 | ~30-36 kcal | ~2.5-3 g |
| 75 lb (34 kg) | 7 to 8 | ~42-48 kcal | ~3.5-4 g |
| 100 lb (45 kg) | 8 to 10 | ~48-60 kcal | ~4-5 g |
Our estimates from USDA FoodData Central values for dry-roasted peanuts (about 28 peanuts per ounce). Not every day; a few times a week is plenty.
How to Serve Peanuts Safely
Peanuts shine as a training reward because a single one smells strong and takes a second to eat. Break each peanut in half and you double the number of rewards for the same calories. For dogs who gulp, a few crushed pieces sprinkled into a snuffle mat turn a tiny snack into a five-minute sniffing game.
- Shell them and check the label says unsalted.
- Chop or crush for small dogs and gulpers to cut the choking risk.
- Use as rewards: one peanut is a strong motivator for training.
- Prefer peanut butter? Choose a jar with no xylitol; see can dogs eat peanut butter and our peanut butter dog treats.
My dog ate a bag of peanuts or shells. A few salted peanuts usually cause nothing worse than thirst. Offer water and watch for 24 to 48 hours. Call your vet if your dog vomits repeatedly, has diarrhea, a painful belly or seems lethargic, which can follow a big fatty meal, or if a small dog swallowed shells. Peanut candy with chocolate or xylitol is an emergency; see dog ate chocolate and xylitol poisoning.
Allergies, Pancreatitis and Other Special Cases
- Allergies: peanut allergy in dogs is very rare, but stop if you see itching, hives, swelling or vomiting.
- Pancreatitis: skip peanuts; the fat can trigger flare-ups. See low-fat foods for dogs with pancreatitis.
- Weight loss: peanuts are calorie-dense; choose lighter rewards.
- Puppies: crushed pieces only, and very few.
Are salted peanuts OK just once? A couple usually only make a dog thirsty, but salt, sugar and seasonings add up. Plain, unsalted and shelled is the only kind I suggest.
What about peanut butter? Read the label every time. Xylitol, sometimes listed as birch sugar, is very dangerous for dogs.

Frequently Asked Questions
Can dogs have peanuts in the shell?
No. Shells are fibrous and can choke a dog or block the intestines.
Can dogs eat salted peanuts?
One or two won’t harm a healthy dog, but salted peanuts shouldn’t be a habit.
Are peanuts good for dogs’ skin?
They contain vitamin E and fats, but a complete diet or a vet-recommended fish oil supports skin far better.
Can dogs have peanuts and cashews?
Yes, a few of each if they are plain and unsalted. Both are fatty, so count them together toward the treat budget.
My dog ate peanut M&Ms. What should I do?
The chocolate is the concern, not the peanut. Note how many your dog ate and their weight, then call your vet or a pet poison line.
Can puppies eat peanuts?
A crushed piece or two is fine for an older puppy. Whole peanuts are a choking risk for small mouths.
Can dogs eat peanuts every day?
A couple a day can fit a large dog’s treat budget, but most dogs do better with peanuts as an occasional reward.
