I agree with not leaving them alone. Darla is 7 weeks old (she'll be 8 weeks on thursday) and I wouldn't leave her alone at this young age. A pet sitter is a great idea or as was also suggested (and even better IMO) a friend or relative who's willing to come over would be the ideal situation. You can't crate them for that long because their bladders are still so small so it would be a little cruel to crate them that long with no bathroom breaks. On the other hand you can't leave them out because puppies that age can get places and into things we would have never thought possible. Inevitably I think opting for a sitter of some sort will be your best bet. Welcome to Yorkie Talk. Good luck with whatever decision you make.
