This snacking favorite is also one of the worst foods that you can ever give your dog. Even as few as six macadamia nuts, regardless if raw or toasted, is enough to make your dog sick, and manifest the poisoning through muscle shakes or tremors, vomiting, high temperature, and paralysis or weakness in the hind legs. Combining this with chocolate will result to more severe symptoms, even fatal.
