I can’t say for sure, but it seems most folks are keeping the pup on an appropriate large breed puppy food until maturity and then beginning to add in extras.
If it were my pup, that is personally what I would do unless you consult with one of NV’s nutritionist and they offer you a solution that will not compromise your babies optimal growth.
One of the regulars on here said something once that really stuck with me about large breed growth. She said essentially that you only have one chance to get a proper orthopedic structure. I thought that was such an eye opening way of looking at this topic.
