It's usually a good idea to keep a puppy on whatever the breeder is feeding for several weeks to a month after you get them, even if you wouldn't normally feed that food.
Merrick is okay, if somewhat overpriced. My dogs did okay on it whenever I fed it (although my cats didn't particularly care for it).
