This is a lot of pooping!!
I would get her on a better quality food...less grains more meat. Nutro is a mid-quality food...not bad, but not great either.
Your puppy should be pooping less on a meat based food, as well need to eat less.
As you can see the the high grain food is going through her.
Read some of the threads and suggestions on the Nutrition forum for a better quality food.
