Feeding a raw diet is okay IF you get it from a supplier that sells raw meat specifically for dogs, cats, etc. If you are buying meat from your local grocery store/butcher shop, most likely it will contain pathogens such as E. coli on it. The meat grinders/cutter, knives, etc. are NOT sterilized since the meat that they are cutting up are meant for PEOPLE and they are expecting people to cook it to the right temperature to kill these pathogens before it is consumed. Plus you would also need the proper supplements and vitamins in the proper amounts. Unless you get it from a legitimate supplier, like Primal, then everything needed is already ground up for you.
It is also not a good idea to mix raw and kibble or change it every other day or so since a dog's stomach takes a long time to adjust to food changes.
I think feeding kibble is fine if it is a HIGH quality food diet such as EVO, Taste of the Wild, Blue, etc.
