Hello from a fellow Tenn resident......
There are several very good breeders around you. But, I am not real confident that you will find what you want in the newspaper. You do want a yorkie to look like a Yorkie.....so, with not knowing the history of the breeder...you may be taking a big risk. And also, you may be at a greater risk for getting a larger or maybe a yorkie mix. If you are adament that you want to use the paper....then go visit the breeders, see the parents and the kennel.
I would also get a book of Yorkies...they will show you what a puppy SHOULD look like as a puppy, then as an older dog.....so you make sure what you buy is indeed a Yorkie and not a Silky.
If I can help feel free to send me a PM.. We live about 20 miles from Nashville.
