getting discouraged?
 

Don't get discouraged.
There are some breeders that are willing to help you get started.
You just have to find them.
You might try www.amazingyorkies.com
She has some nice lines...;)

It will take a VERY ling time to get a good founation bitch. Majority of quality breeders will be very leery and reluctant to let one of their girls go to someone who plans to breed.
I bought my first yorkie (for pet) 5 years ago, a nother a year later. Then I decided I wanted to raise yorkies...still no more yorkies since my first two pets.
I talk with breeder see what they want, I am busy with my life and trying to set it up so that raising yorkies will fit with my lifestyle (I changed careers and became a dog groomer so my pets can come to work with me and I own my own salon so I set my hours, decide when to come to work).
Someday I know there will be a breeder who is willing to part with a yorkie that will be show quality (I feel for my breeding program I want finished yorkies in the show ring) and willing to let a novice have a chance.
It will take time, my quest has been going for 4 years, I want to know everything I can, be prepared. I never want to run into a problem and look back and think, If only I was more prepared, informed, etc.
You will find that yorkie, one for a pet is a great start. For me there is nothing like them, they have a personality of their own, a big dog in a little body!
Talk openly with breeders you are interested in, tell them what you want and ask them what they would want to see you do to acheive a puppy from them.
Good luck, it will be worth the patience and hard work.
