I'm not a breeder, nor am I a super duper experiences yorkie owner.
But here are the reasons I would say any breed that is said to mature 15lbs or under should be kept until 10-12weeks at least.
They are tiny. Much tinier than medium and large breeds at this age. Therefore the extra couple-few weeks with mom will allow them to be a more appropriate size, be abe to handle solid foods better as their teeth come in better, and have a lesser chance of hypoglecemia [sp?] I do believe that they also learn a lot of their manners at 6-10 weeks. But it is the new owners responsibility to keep up with discipline and corrections for biting, housetraining, etc.
Just what I think anyways. Bringing home a black lab at 8 weeks is much different than bringing home a yorkie at 8 weeks. Everything from size, teeth, eyes, how/what they eat because of their size.
