Is raw meat good for my puppy ?

Hi everyone, i have an Eskimo/Spitz 4 months puppy, i feed her "Royal Canin Mini puppy" food, i may switch to "Mini indoor puppy formal 21", i give her Nuvet every morning, and fish oil with her meals, and one spoon of yoghurt everyday, i hear too many people feeding their puppies raw meats, and tell how its very useful for dogs and puppies, so is it ok to feed my puppy raw meat only twice monthly ? coz she already on dry-food diet .
