I've read somewhere that people with larger breeds often feed adult food and skip puppy food because the puppy food pushes them to go too fast.

However, if you do choose to feed a puppy formula, these kibbles seem to have great ingredients (and you'll definitely need a higher quality food if you plan on showing):

-Innova Puppy
-California Natural Puppy
-Chicken Soup for the Dog Lover's Soul Puppy
-Canidae (all life stages)
-Wellness Super5mix Puppy
