I'm sorry this thread didn't get answered sooner. I think it just got lost in the shuffle. My avatar is a picture of Ellie who has a puppy cut. Have you tried "Photo Gallery" at the top of this page? You should see plenty of pics just looking at different threads. I'm surprised you haven't come accross too many with puppy cut since there are lots of them here.
I cut Ellie's hair myself, so I don't know what you tell a groomer to do. Well, actually they usually do exactly what you DON'T want.
Just type in the word "groomer" in the search on YorkieTalk and you will here plenty of stories. The best advice I have for you is to cut hair yourself. If that's not possible go to a reputable groomer and don't say you want your dog to get a puppy cut. Tell them exactly what you want done to each part of the body or they will do what they want.
