Ok i am lost on this. I got stacey caucasian mountain dog book . and in her book it says that moderate  protien level (about 25% )ok but what i am not understanding in the book is  it says  that raw meat is not good for caucasian mountain dogs. Or raw goat meat or cow milk. also in  her book it says you can add high quality canned dog food to the dry kibble or  yogurt or home prepared fresh food.  ??? Help me please
