I need advice on a couple things, but first - I have great news

! About two weeks ago, our baby Bear (who is 6 months now) finally "got it" and is on the road to being potty-trained

. It was weird - one day he peeped anywhere he pleased (he was famous for the walk-a-peep), and the next - he was "potty trained"! I know it's not official until they have less than one accident per month, but I can tell he finally understands!!! Happy days are here again. Between him stopping biting and him learnin to peep on the pad I am one happy Yorkie mom. I had a couple questions for you other Yorkie parents. 1) Our baby has grey hair on his head... is that normal? I read that tan or gold was what it was supposed to be and none of his Yorkie friends have grey... does it matter what color the hair is? 2) Also Bears ears are still down, and we never encouraged them to stand bc we thought people just did that for looks or something, but is there a health reason? :-?
