Can dogs eat almonds?

The detail

A plain almond is roughly half fat by weight, at about 50g of fat per 100g. That is close to the fat content of a pistachio or a peanut, and it is the same reason Vets Now puts nuts generally in the category of foods that can cause stomach upset and potentially pancreatitis.

Shape is the second problem. Almonds are hard, roughly oval and easy for a dog to swallow whole rather than chew, and the ASPCA lists nuts including almonds among the foods whose oils and fats can cause vomiting and diarrhoea in pets. A whole almond swallowed by a small dog can lodge in the throat or gut.

None of this makes almonds an emergency in the way chocolate or grapes are. A dog that has eaten one or two almonds off the kitchen floor is very unlikely to come to harm, but a bag left within reach is a different story.

Whole almonds and the choking risk

A whole almond is small enough to gulp and hard enough to sit undigested, which is the combination Vets Now and the ASPCA both flag for nuts generally. Small and toy breeds are most at risk, because their airway and gut are narrower.

If you want to offer a taste at all, chop the kernel finely rather than handing over the whole nut. That does not remove the fat, but it removes the choking shape.

Salted and flavoured almonds

Salted, smoked and flavoured almonds add a second problem on top of the fat. A 30g handful of salted almonds carries roughly 0.3 to 0.5g of salt, which is a meaningful dose for a small dog on top of everything else in its day.

Flavour coatings are the ones to check hardest. Chilli, barbecue and honey-roast varieties sometimes carry onion or garlic seasoning, and Battersea's toxic food guidance lists the onion family as toxic to dogs whether it is dry, raw or cooked.

If you are sharing at all, plain and unsalted is the only version worth considering, and even then only occasionally.

Almond butter and almond milk

Plain almond butter with nothing added carries the same fat concern as the whole nut, spread thinner. The specific danger is xylitol, and the Pet Poison Helpline says xylitol can cause life-threatening low blood sugar within 10 to 15 minutes and lists sugar-free spreads and supplements among the products that carry it, so check the label before offering a spoonful.

Unsweetened almond milk in a small amount is unlikely to cause a problem beyond an upset stomach in a dog with a sensitive gut, since dogs have no nutritional need for it and it adds nothing water does not. Flavoured or sweetened versions are the ones to leave on the shelf, for the same xylitol reason as almond butter.

Marzipan and Christmas cake

Marzipan is ground almonds bound with a large amount of sugar, and a slice of Christmas cake coated in it stacks the almond fat onto the sugar and, usually, dried fruit underneath. VCA Animal Hospitals and the wider veterinary consensus treat grapes, raisins and currants as capable of causing kidney failure in dogs, and a traditional Christmas cake is built around them.

Treat a stolen slice of marzipan-covered cake as a raisin incident rather than an almond one, and ring your vet with an estimate of how much cake and how much dried fruit it contained. Our dates page covers dried fruit in more detail.

Almonds compared with macadamia nuts

These two get confused because they are both pale, round nuts sold in a similar bag, and only one of them is a genuine poison. VCA Animal Hospitals says macadamia nuts are toxic to dogs, that a few nuts are enough to cause illness, and that signs including vomiting, weakness in the back legs and tremors start 3 to 6 hours after eating.

Almonds carry none of that toxic mechanism. The concern with almonds is fat, salt and choking shape, not a poison, which is why this page sits in amber rather than red.
