theres a lot of info on what to feed a puppy here on the forum. search calcium levels in the forum. You wi get a list of recommended foods based o calcium levels
The thread PugMom suggested is a GREAT one, and helped me figure out what to feed my Presa Canario pup (mastiff).
What you’ll find in the thread is that the protein content for large breeds is not nearly as important as the calcium and phosphorous levels. Hound Dog Mom put together a great list of 4 and 5 star grain free foods for large breed pups.
