Congrats on your soon-to-be new puppy!
I have not had direct experience with Large Breed Puppy nutrition, but here are a few resources that will hopefully help clear things up for you:
Here is a basic article about LBP nutrition, along with a calcium/phosphorus calculator: /best-dog-foods/best-large-breed-puppy-food/
Here is a link to the forum topic about LBP nutrition. In the middle of page 15, there is a link to a list of acceptable LBP foods: /forums/topic/large-and-giant-breed-puppy-nutrition/
Good luck with your new puppy!
