Take things slow. She is in a new environment with new people and new everything -- she needs some time to adjust. Do things at her pace. Never force her into a situation she clearly does not want to be in. It will be slow and frustrating but she will get used to you, I promise.

My Charlie is the exact same way. When I first adopted him, he would hide in his corner the entire time. The only time he would leave was to eat or if we brought him outside. He shyed away from being petted, he would not come to us, his ears were always back and if he had a tail it would have been between his legs 24/7.

But over time, he has warmed up to us a lot. Now Charlie is a more extreme case, I really think he was abused either physically or psychologically, I don't even know for sure.

Even now, he is only "ok" around his dad and I or our roommate because he is home just as much as we are. If a friend comes over and tries petting him, he will freak out and run away.

But you get him around other dogs.... he goes nuts! He is like a completely different dog!!

So my suggestion is to take it SLOW and don't try to force her to stay and be petted if she is uncomfortable with it. That will only make her more scared.
