Whats the best type of raw diet to feed a bullmastiff puppy? Fruit and Veg? yes or no?

at the moment he's eating mostly raw meat n bones (chicken, pork, duck, turkey, lamb n beef), offal(heart, kidney, liver, tripe) and whole fish once a week usually trout, and some bits n pieces of fruit n veg but do i really need to mash the fruit and veg or do they even need fruit n veg? want to make sure he doesnt grow too fast
