It is a good food, it is one that I have thought of switching to.
I didn't use it when my pup was younger because of the higher protein and the calcium levels.
Sawwahbear, you don't want higher calcium levels in a growing pup, That is why a lot of companies make large breed specific puppy food to adjust for the calcium and phosphorus levels. I also didn't like high protein levels because my pup was prone to Pano and that is also thought to conribute to it.
