Nutro Natural Choice or Ultra Puppy?

Hello,

We have a new puppy and looking for food recommendations. The puppy
is a 4 month old Miniature Schnauzer and we're not happy with the food
the breeder was feeding her (Iams mini chunks) and want something
better and for a puppy.

I have always had good luck with Nutro for large breeds when we had
our Lab.

I'm trying to decide between Nutro Natural Choice Lamb and Rice Puppy
or Nutro Ultra Puppy. Does anyone have experience with these or
recommendations one way or the other?

Thanks,
