There are several foods and plants that make dogs sick. In addition to the well-known nightshade plants (tomatoes, peppers) and foods such as chocolate, onion, raisins and grapes, several plants should be kept out of reach of your dogs. If your dog ingests a poison, contact your vet immediately. Before taking the dog to the vet, you may be advised to give the dog hydrogen peroxide to make it vomit. Another treatment for certain poisons is activated charcoal.
