My boy is all yorkie and I got him when he turned a year old. I honestly have no clue what he looked like as a puppy. But, with a yorkie, as well as a mix, sometimes you just have no idea what they will look like once they're "all grown up."
I don't have any pics on my new laptop, but I'll try to pull up some old thread for you to see what he looked like at around 10-11 months old, a year, and now at 2.
