I agree with BC_Mom, dogs do not do things to "get even." However, the going in the house may be a reaction to being left alone. If she has not been left alone she may become anxious and not know what to do or how to behave. This anxiousness may cause her to have to eliminate. Crating her when you are not home is an excellent idea until she learns the rules of your house and how to behave. She isn't doing it to be bad, she just doesn't know any better, or is so anxious she cannot hold it. Two weeks really isn't a long time and she is probably not sure what is expected of her. Be patient and teach her what you want from her, and I am sure that she will happily become a loved and loving member of your family. Good luck, and congratulations.
