Continue putting bows in your male Yorkies hair! I'd use Macho style one though. Give him real cool ones. To offset any girly type bows. I'd try to find the biker kind if they make any...
I saw something on Animal planet last night that I thought was utterly ridiculous.. This is very true. A older woman in L.A. is making dog wigs and selling them! I saw them on yorkies, and on all types of dogs, even the bigger breeds. OMG, I thought how dumb. Dog wigs? Human hair, braids and the whole nine yards on them? some of them were died, pink, blue, and ALL different colors

IMHO that was outrageous. She was selling them , for around $60.00.
Now that is BAD... PLace your bows on your male yorkies, they ought to wear them, they have top knots, and look awesome
