as the man said earlier, play, play and more play, hand feed her but dont stroke while feeding , this can panic nervous dogs, dont reach in and pet her when she lying down either, let her make all the approachs, she may only want her hindquaters rubbed,(what female doesn't), because face to face may be too much emotional interaction at this point in time,, bounce a ball and try to get a responce from her might be just short eye contact or putting her paws up on you, but its positive ,,
i wll do thanks for the advice hope she comes right cheers mb
