Can Dogs Eat Peanuts? What Pet Parents Must Know

Yes, dogs can eat peanuts—with some stipulations. They need to be shelled, dry-roasted or raw, have no added salt and given only in moderation, preferably in the form of peanut butter. As always, it’s crucial to consult your veterinarian before introducing a new food into your pets’ diet. It’s also important to provide them with a small quantity at first, just in case they’re allergic. If you see signs of an allergic reaction when your dogs eat peanuts or peanut butter, contact your veterinarian or an emergency veterinarian immediately. And remember, treats and snacks of all kinds should make up no more than 10 percent of your dog’s daily calories.

Your dog may crave the rich flavor of peanuts and peanut butter—and they’re fine every once in a while—but some peanuts and peanut products could be harmful to your dog. Here are some factors you need to consider when it comes to dogs and peanuts.

Health Benefits of Peanuts for Dogs

Are peanuts good for dogs? Here are some peanut perks:

• Great source of protein
• Contain vitamins B-6 and niacin, which can promote a strong metabolism
• Contain vitamin E, which can promote a strong immune system and aid a variety of other organs
• Contain good fats

There are better snacks out there for your dog, but—if given sparingly—plain shelled peanuts are usually fine as a once-in-awhile treat.

How to Feed Peanuts to Your Dog

Now that you know the answer to the question “Can my dog eat peanuts?” is yes, there are a few precautions you should take when allowing your pup to have this treat. When your dogs eat peanuts, make sure they’re plain, with no added salt or flavorings. If you’ve wondered, “Can dogs eat peanut shells?” the answer is no. Discard shells before feeding peanuts to your dog, and only give a few peanuts every once in a while. Peanuts should not be a daily treat.

If you’ve ever let your dogs eat peanut butter, you’ve probably gotten a positive reaction. A little peanut butter can be an effective incentive when giving medication to pill-averse dogs. Peanut butter can also come in handy as a training reward or a surprising treat when stuffed inside a KONG toy. It can even make bath time more fun—smear a stripe of peanut butter on the tub wall and see what happens. Peanuts and peanut butter are also common ingredients in doggie baked goods recipes.

However, as much as dogs adore the gooey snack, peanut butter tends to be high in sodium and sugar. Many pet parents like to blend their own using just peanuts and their preferred dog-friendly oil—coconut oil can be a good choice. Before giving your dog store-bought peanut butter, read the label to confirm it doesn’t contain xylitol—this is toxic to canines.

Frequently Asked Questions

Can dogs eat peanut butter? Yes — most dogs can enjoy peanut butter in small amounts. Look for varieties made with only peanuts (and perhaps a little salt), and always read the ingredient label carefully before sharing it with your dog. Because peanut butter tends to be calorie-dense, keep portions small and treat it as an occasional reward rather than a daily staple. Treats of all kinds — including peanut butter — should make up no more than 10% of your dog's daily caloric intake. https://sites.tufts.edu/petfoodology/

What is xylitol, and why is it dangerous for dogs? Xylitol is an artificial sweetener found in some "natural" or reduced-sugar peanut butters, as well as in gum, candy and baked goods. It is toxic to dogs even in small quantities and can cause a rapid drop in blood sugar or, in larger amounts, liver damage. Always scan the ingredient list for xylitol — or any sugar alcohol ending in "-ol" — before offering your dog a peanut butter product. If you suspect your dog has ingested xylitol, contact your veterinarian or the ASPCA Animal Poison Control Center immediately. https://www.aspca.org/pet-care/animal-poison-control

How much peanut butter is safe for a dog? There is no universal serving size that applies to every dog, because the right amount depends on your dog's size, weight and overall diet. A general guideline is to keep all treats — peanut butter included — at or below 10% of your dog's total daily calories. For a small dog, that may mean just a lick or two; for a larger dog, a teaspoon-sized portion is a reasonable occasional treat. When in doubt, ask your veterinarian to help you calculate an appropriate amount for your individual dog. https://sites.tufts.edu/petfoodology/

What are the signs of a peanut allergy in dogs? Food sensitivities in dogs can show up as skin-related symptoms — such as itching, redness, hives or swelling — as well as digestive upset including vomiting or diarrhea. In rare cases, a dog may experience a more severe allergic reaction. If you notice any of these signs after your dog eats peanuts or peanut butter, stop offering the food right away and contact your veterinarian or an emergency veterinary clinic. Always introduce any new food in a very small amount first so you can watch for a reaction before offering more. https://www.aspca.org/pet-care/animal-poison-control

Can dogs eat peanut shells? No. Peanut shells are a choking hazard and can be difficult for dogs to digest, potentially causing gastrointestinal irritation or a blockage — especially in smaller dogs. Always remove shells completely before offering peanuts to your dog, and discard them where your dog cannot access them.

Are salted or flavored peanuts safe for dogs? Plain, unsalted peanuts are the only variety recommended for dogs. Added salt can contribute to excessive sodium intake, and flavored varieties — such as honey-roasted, spicy or seasoned peanuts — often contain sugars, spices or other ingredients that are not appropriate for dogs. Stick to dry-roasted or raw peanuts with no added salt or seasonings, and always check ingredient labels for anything unfamiliar before sharing with your dog. https://www.aspca.org/pet-care/animal-poison-control
