As a puppy Neapolitan Mastiff's need a low protien food, around 26%. To fast of growth causes growing problem in the giant breeds. Low protien slows the growth. Also, no soy. No one brand is best and everyone has the one they love, so just look for one that does not have corn as a first ingredient, generally chicken or chicken products.
