Along with the links that 14+ gave you, I strongly suggest checking out Dog Star Daily
. There's tons of info there on how to deal with pretty much everything a puppy can throw at you. Start with this page, and make sure you read the "Errorless Housetraining", "Errorless Chewtoy Training", "Home Alone", and "Puppy Playroom and Doggy Den" articles: http://www.dogstardaily.com/training...home-8-9-weeks
They may just save your sanity (and your sheets)!
