Can dogs eat it?

Can dogs eat cashews?

Only with care One or two plain, unsalted cashews will not hurt most dogs, but they are fatty, often salted, and mixed packs can hide macadamias.

Why

Sources differ. AKC says cashews are not toxic and a few unsalted ones are fine occasionally, while RSPCA Australia lists nuts among foods never to feed. Cashews are high in fat, which can lead to pancreatitis and weight gain, are usually salted, and are often sold in mixed packs with toxic macadamia nuts.

Signs to watch for

If your dog ate cashews

Check whether the pack contained macadamias or chocolate. If it did, or your dog ate a lot, call your vet.

If your dog has eaten something toxic

Call your vet or the nearest emergency vet now. Do not wait for signs, and do not make your dog sick unless a vet tells you to. Take the packet with you.

How to give it safely

If you share, one or two plain, unsalted cashews on their own, never from a mixed pack.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.

Other foods people ask about

Almonds Only with care Best not. Almonds are not toxic like macadamias, but they are hard to digest, fatty, and can block the throat or gut. Hazelnuts Only with care Best avoided. Hazelnuts are not toxic, but they are fatty, a choking risk, and the hard shells can block the gut. Macadamia nuts No, toxic No. Macadamia nuts cause weakness, wobbliness, vomiting and a raised temperature in dogs. Call your vet if your dog eats any. Peanut butter Only with care Yes, if it has no xylitol. Check the label for xylitol or birch sugar every time, and keep it small because it is high in fat. Peanuts Only with care A few plain, unsalted, shelled peanuts will not hurt most dogs, but they are fatty and salted or flavoured ones are best avoided. Pecans No, toxic No. Pecans contain juglone and can carry toxic moulds, and like other nuts they are very fatty. Keep them away from your dog.
