Nutro, unfortuantely is not a good recommendation for Yorkies either

.
I personally feed INNOVA puppy (lots of YT'ers feed this as well) it is a great food for a growing Yorkie Puppy! after Gucci is an adult I will switch over to EVO made by the Innova Company.
Other recommendations are:
Orijen
Nature's Variety
Natural Balance (Dick Van Patten)
Wellness
and I am sure others can add more.
These are all GREAT Foods for Yorkies and any other dogs. I know they can be a bit pricey but really there is NO COST for your babies health and nutrition and if you think about how little they eat (as you already have

) you will see it isn't but maybe $20 a month or in my case $20 for 2.5 months to feed your baby.
Hope that helps!!
Can't wait to see the pics of her grooming..
