I think it's hard for the average person not to leave their yorkie home alone. Mr. Biggs is onyl ever really alone for 4 or 5 hours at a time while my BF and I are at work and school and such. Since he's fully trained, he has complete run of the house. I know he loves it, because when we come home all of his toys (and I do mean ALL of them) and scattered around the house! Plus, it's the best feeling in the world to be welcomed home by tons of yorkie kisses.
