Do you know her history? Is she afraid of certain noises? If she had always lived in a cage/crate and never went out, she could be afraid of the grass/floor, etc. It sounds as if she has never been socialized to the outside world. Do you leave a leash on her when she is away from you? I have had to do this with unsocialized dogs so I could get to the leash without getting too close to them so they run from me. Since she is older, it will take more time than usual. The first tests I have done on a dog like this is a complete thyroid and an eye exam.
