Ive noticed that Izzy sheds a little too. Its not much, but I notice hair on one of the rugs in my bedroom and when I comb his hair a little bit comes out on the comb. It sounds like from the other posts that this is not normal because yorkies dont shed, but I was under the impression that their hair is like human hair and when you comb it it comes out a little and you will find strands of hair around...mine does that. I dont have any issues with my hair falling...I have plenty of it!
He is a full bred yorkie, maybe I should check into allergies too?
