Peanut
CautionPeanuts are not chemically toxic to dogs, but the AKC allows only dry-roasted or raw, unsalted, shelled peanuts, just a few at a time and not every day. Salt, fat and the shells are what cause the trouble.

More about this food
Peanuts are legumes, not tree nuts, and they carry none of the toxin that makes macadamias an emergency. The American Kennel Club says dogs can have them -- with conditions, and the conditions are the whole story. The AKC's line is that dry-roasted or raw, unsalted peanuts are the only peanuts safe for dogs, that you should remove the shell because the fibrous material is a choking hazard especially for small breeds, and that you should limit your dog to just a few peanuts rather than making it a daily treat.
Salt is the first issue. Almost every peanut sold as a snack is salted, and the AKC notes salted peanuts carry more sodium than a dog needs and can be harmful in quantity. Honey-roasted peanuts and flavored peanuts are explicitly off the list -- those add sugar and seasoning blends that frequently include onion and garlic powder.
Fat is the second. Peanuts are high in fat, which produces digestive upset in the short run and pancreatitis when a dog eats high-fat food regularly or in large amounts. Pancreatitis usually shows up 24 to 72 hours later: refusing food, repeated vomiting, a praying posture with chest down and rear up, and pain when you touch the belly. That combination is a same-day veterinary visit.
Shells are the third. Ballpark peanuts, boiled peanuts and peanuts in the shell all go down whole with an enthusiastic dog, and peanut hulls do not break down in the gut. Repeated unproductive retching, drooling, or an inability to swallow is an emergency.
Storage is the fourth. Peanuts support Aspergillus growth and aflatoxin production, so stale, damp or bitter-tasting peanuts should never go to a dog. And while true nut allergy is uncommon in dogs, facial swelling, hives or frantic itching after a first exposure means stop and call.
What to do right now: a medium or large dog that stole a few unsalted peanuts usually just needs 12 to 24 hours of watching for vomiting, diarrhea and appetite change. A dog that emptied a can of cocktail peanuts, swallowed shells, or is small and ate a lot should get a call to your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435. Do not induce vomiting at home -- shells can lodge in the esophagus on the way back up, and that call belongs to your vet. Xylitol-free peanut butter is a separate story: check the label for xylitol or birch sugar and it stays a usable treat.
Frequently asked questions
- My dog grabbed a few peanuts off the floor. Emergency?
- A few unsalted peanuts rarely cause more than mild stomach upset in a medium or large dog. Watch 12 to 24 hours for vomiting, diarrhea and appetite. If shells went down too, or your dog is small, watch closely for retching or drooling and call your vet.
- What about peanuts in the shell from the ballpark?
- Skip them. Those are salted, and the AKC specifically warns that the fibrous shell is a choking hazard, especially in small breeds. Shelled, unsalted, dry-roasted peanuts are the only version worth offering, and only a few.
- If peanut butter is fine, why be careful with peanuts?
- Form is the difference. Xylitol-free peanut butter has no shell to choke on and is easy to portion. Whole peanuts arrive with salt and hulls, and a dog can swallow a large fatty dose in seconds, which is how choking and pancreatitis happen.
