I think a raw food diet can be good if done properly. There has to be other ingredients besides just the meat. You can get a lot of good info online about raw diets. My little one eats Stella & Chewy's freeze dried raw food mixed with a kibble. If it was up to her all she would eat is the S&C's. She has done very well on it so far. I believe supplements are very helpful for dogs that seem to be lacking in certain areas of their health like skin and coat or weight.
