Something else you have to consider here to is that according to what you said in your 1st post here, you have only had this dog for 2 weeks. I personally will not work with a dog (rescue or just adopted) within that time frame since the dog is not yet totally settled into its new home. Usually I will try to wait at least a month so that the dog has time to warm up and all that good stuff before I try to help some one with training. I will however give them pointers and that kind of thing to help the dog warm up to them. Expecting this poor little dog to come out of her shell in such a short time and then to have some strange man working with her is (IMHO) going to cause more harm then good.
Give her a little more time to settle into your home. As you have said she came from a not so good situation so she needs some time to relax and settle in.
