Puppy food should not be started (if at all) until after the puppies are whelped. The increased in calcium prior to whelp can in many cases imcrease the likilyhood of eclampsia.
Although I personally do start mothers on puppy food after whelp, I know many breeders that no longer follow that practice and feed only a good balanced adult food to both puppies and adults. They have been very successful with this. I am hesitant to change my practice as I am a firm believer in "If it ain't broke - don't fix it". :-)
Best of luck what ever you decide to do.
