A single small piece of Brazil nut occasionally is unlikely to cause harm, but their very high fat content and large size relative to other nuts make them a poor regular treat.
Brazil nuts aren't associated with a specific toxin the way macadamias or mouldy walnuts are, but they're among the highest-fat nuts commonly available, and their size is a genuine choking risk for smaller dogs.
