I am from Buffalo, NY and bought my Lulu from a breeder in Hilton, NY, right outside of Rochester. His name is Bob Balas and he owns Mistibleu Yorkies. His website is
yorkie puppys for sale, teacup yourkies for sales, quality breed Yorkie's for sale. His Yorkies are litterbox trained and have their shots plus they are spayed/neutered before you get them. So, while they might seem a bit expensive, you do get good quality for your money.
I just love Lulu. She has the best personality and is very lovable. Bob has some really cute boys available on his website right now.
Good Luck!!
