Don't hit your pup for going in the house. The attitude I went with when I got mine, is that when they make mistakes, it is MY fault. Take her out more, play with her more, and ignore her when she bites. If you 2 are playing, and she starts biting, ignore her and walk away. When she is ready to play nice again, you can play again. Eventually she will learn that the biting results in no more play time, and hopefully she will stop.
Does she have an adequate amount of toys and chewies to stimulate her? She may get bored sometimes. I know those little puppy teeth can hurt!!!
