I swear by the book "HouseBreak your Dog in 7 Days". It is a wealth of info and gives sensible crating timetables based on the age of your pup. 7 Days? I'd never want to push a dog that quickly and expect prefect house manners after 1 week, but its helpful to have a game-plan that is spelled out for EVERYONE in the house to follow! :)
Good luck and give your new pup a hug for me!
