-Barking isn't an issue for me at all. Wobie whines a lot when he's lonely, but a simple "quiet" will stop that.
- In my opinion, yorkies need a lot of attention. The more time they spend with their family, the happier they are. I think your baby will be fine by himself all day, as long as the minute you get home, and on weekends, you are devoted to giving him attention and love. I have a feeling that this may not be practical in a family with two parents working full-time and two children in highschool, because life is just too busy.
-Wobie chases my family's cats. There are 12, so its hard to keep them separate. I'm working very hard on training, but I'm having very little luck with that...
Good luck with your decision.
