#5 Is VERY surprising 1.) Coffee/Chocolate: Both of these popular food items can cause a high heart rate,tremors, seizures and even death 2.) Alcohol: Can Induce Seizures, Coma and Death! 3.)Avocado: Can Cause Vomiting and Diarrhea 4.) Macadamia Nuts: Can Cause Hind Leg Weakness, Paralysis and Tremors. 5.) Rawhide- DO NOT give your dog rawhide for any occasion. Their stomachs don't have the necessary enzymes needed to break the rawhide down and in turn this can cause death. 6
