I'm sure she is loving the time you are giving her and the time when you are not available she is just looking forward in you arrival home. treasure the time together. do something a little extra special with her, like taking her out for icecream or a picinic when you have the chance. I don't have a yorkie yet but I have been looking for one for quite sometime, I have another dog that I do special things with, she loves it and treasures those moments.
