Sounds like your ready for another Yorkie! The only suggestion I would have is how active is your current baby? If you get a tiny puppy, she's going to want to play all the time and sometimes our older ones don't have that kind of patience! Maybe one that's 1-2 years old would be better for both of you, there are lots of yorkies that need to be rescued out there. I would get a female for sure, and take your girl with you when you find one and see what kind of reaction you get with both of them together. Sometimes putting younger ones with older ones help the senior out a lot, it gives them companionship and extra exercise that they need. Good luck...
