TX. Since your funds are limited; If having a pup is not extremely important to you, you could check out some Yorkie Rescues or go to petfinder.com. Even then you can sometimes find a pup. I have seen quite a few really nice Yorkies, some as young as nine months (or) perhaps consider too a mix. I have a Yorkie Poo and she's great and I have a Morkie which is 1/2 Maltese and 1/2 Yorkie (she's on my avatar). I know on petfinder you would have a pretty good shot of getting a young pup if it were mixed with something. Oh and the best part is that by adopting through rescue the adoption fee (anywhere fro $250 - $400 generally) would also cover shots, and spay neuter. Just some thoughts. Best of luck to you
