Can Dogs Eat Peanuts?
Wondering if dogs can eat peanuts? They won't poison your dog, but we don't recommend them due to the choking risk and high fat content.

Whether it's a dropped peanut at a barbecue or a handful left out in a bowl over Christmas, most Aussie dog owners have wondered at some point if a peanut here and there is anything to worry about.
Plain, unsalted peanuts aren't toxic to dogs, but we don't recommend them as a treat. The shell and the whole nut are a choking and blockage risk, especially to small dogs, and peanuts are high in fat, which can contribute to weight gain and pancreatitis. If your dog eats a peanut or two by accident, it's unlikely to cause serious harm, but they're not something we'd suggest offering on purpose.
Are peanuts toxic for dogs?
No, peanuts aren't toxic to dogs the way grapes, onions or chocolate are. That said, not being toxic isn't the same as being a good treat choice. Our view is that the risks peanuts carry, choking and fat content in particular, outweigh any benefit, so we don't recommend feeding them to your dog, even occasionally.
First, the shell and the whole nut itself are a genuine choking hazard and a risk of digestive obstruction, particularly in small dogs. Peanuts are small, hard and easy to swallow without much chewing.
Second, peanuts are high in fat. Regularly feeding high fat treats can contribute to weight gain and, in some dogs, trigger pancreatitis, a painful and often very serious inflammation of the pancreas. Neither risk is dramatic from a single peanut, but there's no upside that makes it worth taking on.
Are salted or flavoured peanuts a bigger risk?
Yes, salted or flavoured peanuts are worse again. Salted, honey roasted, chocolate coated or flavoured peanuts, including the party mixes that come out over Christmas and NYE, add sodium and sugar on top of the existing choking and fat concerns. A simple habit worth building before any gathering: ask guests to keep snack bowls up on the bench rather than a low coffee table your dog can reach.
For more on what else to watch for at this time of year, see our guide to Christmas foods toxic to pets.
Can old or damp peanuts make my dog sick?
Yes, and it's a risk most people don't think about. Peanuts that are old, damp or poorly stored can develop a mould that produces aflatoxin, a toxin that's harmful to the liver. It's more likely with peanuts left sitting out at a barbecue in the heat, or forgotten at the back of the pantry, than with a fresh, sealed packet. If your dog gets into a stash of old peanuts, watch for vomiting, lethargy or yellowing of the gums, and call your vet if you're worried. This is another reason we'd rather pet parents skip peanuts altogether than try to judge freshness.

How is this different from peanut butter?
Whole peanuts and peanut butter carry different risks, which is why our advice differs. The shell and choking risk that make us steer away from whole peanuts don't apply to peanut butter, since there's no shell and no whole nut to swallow. Peanut butter has its own thing to watch for instead: xylitol, a sugar substitute in some brands that's highly toxic to dogs even in tiny amounts.
Our guide to can dogs eat peanut butter covers that all this in more detail.
What should I do if my dog eats a peanut or a handful?
If your dog's snuck a peanut or two, try not to panic, it's unlikely to cause serious harm and isn't a reason to call the vet on its own. Keep an eye on them for a few minutes in case of choking, especially if the shell was still on. If they've eaten a large handful, a mix of salted or flavoured peanuts, or anything that looked or smelled off, it's worth calling your vet for advice. Going forward, a purpose made dog treat is a safer way to reward your dog than peanuts, whether it happened by accident or you were thinking of offering some.
FAQs
Peanuts aren't toxic to dogs, but the choking risk and fat content mean we don't recommend feeding them, even occasionally. If your dog gets into some by accident, keep an eye on them and call your vet if anything seems off, but there's no need to make peanuts part of your dog's regular treat rotation.
