Because you want the best for your dog, you most likely have heard a lot about natural dog food as of late. It actually is a great way to provide the necessary nutrients to your dog and nothing else. It does not have all the fillers and preservatives that traditional dog food has, so you are ensuring that your dog is not consuming anything extra. When you start your dog on this natural diet, it is best to start out slowly to make sure that your dog does not react to the food. The reason this could happen is that your pet is so used to his normal food that his body might not recognize the natural food.
