I will be getting an 8 week puppy soon and I expressed my interest to the breeder on switching the puppy over to Fromm LBP when I receive him. The breeder recommends to keep the puppy on the same food they feed for at least a month. They currently feed Solid Gold Lil Boss and I see that it is for small breed dogs and puppies. Does the recommendation seem adequate for a GSD puppy? Thanks!
