I think people that work can give a yorkie as good of a life as those that don't. I work and I give my girl time before and after I come from work. My girl is as happy as can be. She wakes me up in the morning barking to go potty, then she pics up her toys looks at me and barks with her toy in the mouth so that I could play with her, she gets next to my bed and barks so we can take naps, she asks me to hurryup when I am getting ready to go to work, she doesn't like me to close the door to our room and if I close it she scratches it so I can keep it open. Why all these expplanitions you may ask? Well this just shows that me and my girl know and communicate great and I work.
This is just to mention a few things.
