Hi...Lots of people get what's called a Puppy Cut - it's adorable - short on the face and shorter on the body - Then there IS a schnauser cut - which is self explanatory - What I would do.... is look in the gallery/albums or on the net for pictures of what you like.... and print one out when you see it...
As far as how long it takes to grow to the ground - that depends on the yorkie - and really..long hair is hard to keep up with...It's work and you have to be serious about every day grooming or you'll end up with matts or knots...Chanel had her full coat touching the ground at 1-1/2 years old ...but she has hair that grows really fast. Back then...it was so much work I got her cut in a puppy cut and she looked adorable
This is a good grooming link - I groom my girls but I took them to get professionally done for a long time - I just got tired of bad cuts and high prices - Good luck !
