TailVilleWhy
Peanuts are legumes, not true nuts, and aren't toxic to dogs or cats. They're fatty, though, so too many can cause vomiting, diarrhea or pancreatitis, and whole peanuts can choke small dogs. Salted, honey-roasted or chocolate-coated peanuts should be avoided. A few pets have peanut allergies.
How to give it / if eaten
Shell and skin plain, unsalted roasted peanuts and crush them; give one or two to small dogs or a few to large dogs, only occasionally. Cats don't need them. Start with a single peanut and watch for itching or stomach upset.
Watch for these signs
Too many may cause vomiting, diarrhea or lethargy. Salted peanuts can bring extreme thirst, and excess fat can lead to repeated vomiting and belly pain (pancreatitis) over 1โ3 days. Allergic reactions show as itching, facial swelling or hives.
FAQ
My dog ate peanuts in the shell. Is that okay?
Shells aren't toxic but they're indigestible and can block the gut in quantity. If it was just a few, watch the stool and call your vet if vomiting or constipation develops.
How is this different from peanut butter?
Same ingredient, but some peanut butters add xylitol, salt or sugar, so labels matter even more. See our peanut butter page too.
