Can dogs eat Nuts?
In small amounts, with care
In moderation at most, and honestly best skipped - no nut is a good dog treat. Macadamias are outright toxic, and the rest are fatty, hard to digest and a choking risk.

What happens
Nuts are a mixed bag, and the safest way to treat the whole bowl is as off-limits. Macadamia nuts are genuinely toxic to dogs and can cause weakness and tremors. The rest - almonds, walnuts, pecans, cashews, pistachios, brazils - are not toxic in the same way, but they are dense in fat, hard for dogs to digest, and shaped perfectly to choke a small dog or block a gut. Old or mouldy nuts, including windfalls under garden trees, can carry mould toxins that cause tremors. Salted and flavoured nuts pile salt and seasonings on top.
How much is safe?
There is no nut a dog needs. A stray plain peanut or cashew off the floor is not a crisis, but nuts should not be a deliberate treat. Macadamia nuts are the exception with no leeway at all - any amount is a reason to ring the vet.
How to prepare it
There is no preparation that turns nuts into a good dog treat, so keep the nut bowl, baking nuts, trail mixes and flavoured nut snacks out of reach. On autumn walks, watch for fallen nuts, which are often mouldy. A safe vegetable or a purpose-made chew beats a nut every time.
Symptoms to watch for
A fatty nut binge can cause vomiting, diarrhoea and sometimes pancreatitis - repeated vomiting, a painful belly and lethargy. Whole nuts can choke or block, especially in small dogs. Macadamias cause weakness, wobbly back legs and tremors; mouldy nuts can trigger tremors and seizures.
When to call the vet
If your dog eats macadamia nuts, mouldy nuts or a large quantity of any nut, contact your vet. Choking, repeated vomiting, tremors, weakness or a painful belly after nuts all warrant a prompt call.

Common questions
Which nuts are toxic to dogs?
Macadamia nuts are the outright toxic ones - even a few can cause weakness and tremors. Most other nuts are not toxic as such, but they are fatty, hard to digest and a choking risk, so none of them make a good treat.
My dog ate a walnut on a walk - should I worry?
One fresh walnut is usually just a monitor-at-home situation, but windfall nuts are often mouldy, and mouldy nuts can cause tremors and seizures. If the nut was old or your dog starts trembling or vomiting, call your vet.
Are any nuts safe for dogs?
Plain unsalted peanuts and cashews are the least bad in small numbers, but every nut is fatty and a choking risk, so none is worth making a habit of. If you want a crunchy treat, a carrot does the job for a fraction of the calories.
