You need to take into consideration the amount of care Yorkie's require also. They do require bathing and grooming alot more so than other dogs. Their sorta like having a child. Did you say the one you are wanting is potty trained? That is another thing I have heard that they are very hard to house break and I totally agree with that one. It took me almost a year to get my Yorkie to understand and I'm home with her most all the time and she still will use my rug as a toilet once in a while. You metioned the hours you and your fiance work and I would hate for you to get fed up with this dog every time you come home and find little presents all over the floor. I felt that way about mine and like I said, I'm home with her most of the time. But I do have to say they are very sweet and lovable dogs, just alot of up keep. Let us all know what you decide.
