She is adorable! I am so sorry for your loss. I know how you feel. They leave a hole that can only be helped by another yorkie pup. I say not to replace them but to honor them. I have done almost the same thing. I lost my girl Sadie and over a year later I got little Annie. Annie is from the same line as both my male and the female Sadie I lost. Her mother was Sadie's sister and her father is a son of the same father as my male Ben. So, I too kept the bloodline -- that makes her feel more special for our family. I think that will be the same for you. She is such a close relative of your first yorkie it is like a part of her lives on.
