Levi would be miserable if he were left alone for that long - and I can't imagine the potty accidents! I understand having to work (I am gone 8 hours a day), but I'd never feel comfortable leaving my little man alone that long. I am lucky to have a pretty flexible schedule and a brother that is around to play with Levi, walk him, feed him, and love him during the day. Even on an 8-hour workday, I'd still have a dogwalker come in midday or send him to daycare. I can't imagine a little Yorkie alone for 12-14 hours multiple times every week. Yorkies love their people and need companionship.
