Dogs should not eat macadamia nuts or foods containing macadamia nuts because they can be fatal. As few as six raw or roasted macadamia nuts can make a dog ill. Symptoms of poisoning include muscle tremors, weakness or paralysis of the hindquarters, vomiting, elevated body temperature, and rapid heart rate. Eating chocolate with the nuts will make symptoms worse, possibly leading to death.
