This is why I say to check with your breeder, if there is one, and with a Vet too, if you really want to. You may get answers here from people who have good intentions, but are only giving an opinion.
My Vet says to keep feeding as I am until Diamond's a year old. Whereas Mona's breeder gave her completely different instructions. In this case, we're both right as we sought professional advice of someone who knows our dogs. Talk to your Vet or breeder and see what they say. Your breeder would know the lineage and how the dog should grow on certain foods. They would be your best source of information.
Good luck in making your decision.
