Can Dogs Eat Cake? Toxic Ingredients to Watch For

Can Dogs Eat Cake?

AVOID

AVOID — Cake is high in sugar and fat and often contains chocolate, raisins or xylitol. A tiny plain crumb is unlikely to harm, but it is not a suitable treat.

Cake offers dogs nothing useful and can contain toxic ingredients such as chocolate, raisins, xylitol, macadamia nuts or nutmeg. Choose a dog-safe treat instead.

If your dog ate a small bite of plain cake, watch for stomach upset. Contact your veterinarian if your dog ate a slice or more, or the cake contained raisins or nuts. If the cake contained chocolate or the label lists xylitol, contact a veterinarian, or an emergency veterinary clinic out of hours, straight away, even if your dog seems well.

The full answer

A crumb of plain sponge cake dropped on the floor is unlikely to harm a healthy dog, but cake is not a treat we would offer. It is high in sugar and fat, which can cause stomach upset and, in some dogs, pancreatitis.

The bigger worry is what is in it. Chocolate cake contains chocolate, which is toxic. Fruit cakes may contain raisins, sultanas or currants, which are toxic. Some sugar-free cakes and icings contain xylitol, which is dangerous. Other cakes may include macadamia nuts, coffee, alcohol or nutmeg.

If you want to celebrate a birthday, a dog-safe treat is a much better option. Ask your vet for suggestions suited to your dog.
