Can Dogs Eat Nuts?
It depends on the nut. Macadamia nuts and black walnuts are toxic to dogs and must be avoided completely. Others like plain peanuts and cashews are not toxic and are okay in tiny amounts, but all nuts are high in fat (a pancreatitis risk), often salted, and can be a choking or blockage hazard. In short, nuts are never a great treat for dogs - a few dog-safe fruits or vegetables are a better choice.
It depends entirely on the nut. Some nuts are outright toxic to dogs, while others are merely a bad idea. Because a couple of common nuts are genuinely dangerous, it’s safest to treat nuts as a food to generally keep away from your dog.
Toxic nuts - never feed these
- Macadamia nuts are toxic to dogs. Even a small amount can cause vomiting, weakness, wobbliness (ataxia), tremors and overheating. If your dog eats any, call your vet.
- Black walnuts (and mouldy walnuts of any kind) are also toxic and can cause tremors and seizures. Mould on any nut is dangerous.
Not toxic, but best avoided
- Almonds aren’t poisonous, but dogs don’t digest them well; swallowed whole they can cause choking or a blockage, and they’re high in fat.
- Pecans can carry a mould toxin and are high in fat - skip them.
Generally safe in tiny amounts
- Peanuts (technically a legume) - plain, unsalted, shelled, and only a few. Plain peanut butter is a popular treat, but check it contains no xylitol, which is deadly to dogs.
- Cashews - not toxic, fine as an occasional plain, unsalted nibble, but high in fat.
Why nuts aren’t a great treat anyway
Even the “safe” nuts share problems:
- High fat - can trigger pancreatitis, a painful and serious condition, and add unwanted calories.
- Salt and seasonings - most packaged nuts are salted or flavoured, which isn’t good for dogs.
- Choking and blockages - especially for small dogs.
Because of all this, there’s no real benefit to feeding nuts. If you want a treat, a few pieces of dog-safe fruit or veg (like carrot or blueberries) is a healthier choice.
If your dog eats the wrong nut
If your dog gets into macadamia nuts, black walnuts, mouldy nuts, or a large quantity of any nut, call your vet or a pet poison helpline. Note what and how much was eaten, and watch for vomiting, weakness, tremors or wobbliness.
