Congratulations first of all on your new adoption.  Have you contacted the place where you adopted her from and find out what kind of potty training they have tried with her?  That might be a first step.  If she has not been trained there are a lot of pet stores that offer training for dogs.  You could also get on the web and search for help with the problem.  I am not a dog owner (I only have cats) so I can only make suggestions.  Hopefully someone with a pup like yours will read your post as well and be able to offer more options.  I wish you great success with her training and again congrats!!
