OMG! I had terrible anxiety over this very issue. After I got Bailey, I felt so selfish because I chose to get her and work at the same time.
I know several have more than one yorkie to keep each other company during the day - but that's not for us, either. I calmed down after my husband promised to get Bailey out of the expen when he got home (about an hour before me). He takes her out and feeds her. Its their alone time and he LOVES it. Its was a huge relief for me because I can't always get off at 5:00 to let her out.
Routine is very important for our babies- Bailey knows and expects our routine just fine. I've read several posts that some have placed web cams or nanny cams to watch 'em during the day - all reported that the babies pretty much sleep, anyway.
I hope this post helps.
