Aww you must be so excited and thrilled at the thought about getting another yorkie!
I honestly, if I didn't have a daughter, wasn't pregnant again and had my own place, i'd love to get another yorkie (they are so fun and addicting!) but i have enough responsibilities as it is and would probably pick shopping.. but financially i would just use the money to pay the bills! lol..
i'm sure whatever you choose will make you happy
