Hi there Riley is so cute
Is this your first puppy? Georgie was my first in a long time and my first Yorkie. Here are a couple of suggestions:
Make sure you have nutrical handy, they are so small they don't have any reserves.
Be prepared to take care of a baby, because thats what it's like.
Give him a ton of love, they are sooo wonderful I look at Georgie everyday and think he is amazing.
Again congrats and I am sure other people will give you great advice
