Presumably you do fresh food rather than commercial because you want to improve over their paradigm of nutrition.
The larger the puppy, the nutrients will comprise a smaller percentage of the raw energy input. As the puppy grows, that goes down even more. There's a very great upper tolerance for more nutrients so commercial diets simply over-supplement like crazy. but we still don't know what effect that has had on large breed dogs.
Back when puppies were raised on "whatever" at home, the diets were high in carbs but with nice fresh bones too - and puppies self-regulated - the larger the puppy, the more they tended to eat the carby stuff, while the bones and meat were distributed evenly.
Not to mention there was probably greater tolerance for trashy diets among the more roughly-bred general dog population of 75 years ago and before.
Ironically, I spent less on Lynn's consultation and diet, than I would have to feed something like Orijen puppy, Core, or Eagle Pack, which are pretty much the only commercial sources I now trust - sort of. When she spent a couple weeks with a friend I couldn't believe how much her food cost.
