We found a good groomer through our local Yorkie meetup club (
www.meetup.com then look for owners of Yorkies, if you sign up it doesn't mean you have to attend but you can look at the pics of their Yorkies). But while we were searching, I googled "Yorkie images" and "Yorkshire terrier images" and found several cute pictures of cuts we liked which we printed out to show the groomers. We went to a couple of different ones before we found the one we like, and she's reasonable!
Btw, I could put up a pic of her cut if you like when I get home and you can see if it's what you want. The one in the pic I have as my avatar is before she got her hair cut. The groomer calls her current cut a puppy cut but it's definitely not a poodle cut.
