I dunno. I am SO equal rights about everything and try to be such a well-rounded and open-minded person, that I hate to be guilty of such a double standard, but ...
NO BOWS on my boy!

Ozzie would hate it anyway, but even so.
I do, however, keep a very open mind about others doing it. If you like it, great! And so much the better if you have a pup that WANTS it.
With our first Yorkie, when we took him to the groomer would always tell them NO BOWS. Sometimes, they did it anyway and poor Scruff, he hated it so much. He would begin slamming his head down to get it off the second he got in the car.
