She is just a baby and you are really expecting way too much from her. If you are leaving her to have the run of the house while you are gone she is going to get into everything and have a free for all. You need to confine her either to a crate, Xpen or a small room. She is tearing things up because she is board. If you are gone for more than a few hours you cannot expect her to hold her pee and poop for longer than that. How many hours at a time are you leaving her alone? Are you taking her for walks or outside before you leave? You should not punish her for having accidents inside you house as this will accomplish nothing except that she will fear you. You need to use praise and attention when it comes to a puppy. If you are not able to give your little girl this them maybe it is time to give her to someone that will. I am not trying to judge you but at the same time, if you are not able to give love, praise and attention at this very young age she could very well never become the pet that you are hoping for. They do not just "get it" without a lot of time spent helping them "get it".
