she is very cute!! Being that she is a mix it will be hard to tell what her coat will be like. If its course already, she may end up with more of a poodle coat. You will no more when she gets older, their coats change rapidly untill they are a year old or so.
I too have a yorkie poo, his mom was a full bred toy poodle and his dad is a yorkie poo, my tucker (7 months old) looks identical to a yorkie except for his solid coloring. He is all cream. Good luck with your new pup.
