Our Angel is like that, but he has never been attacked! We got him at nine weeks old! Unfortunately, we just have a chi with bad genes.
However, I am determined to break him of his bad habits. There are "work-arounds" I am using for the interim. If he is somewhere I don't want him, like if he gets on a chair uninvited, I simply say "off" and he gets down. Then I can pick him up. He is not allowed on furniture, not allowed in my lap unless I tell him it's okay. Three days ago he bit twice, and he got me good! Each time it was because I was taking him outside when he didn't want to go. That is not acceptable for me! So I have to work on it. Also, if he is sleeping, anywhere, be it in his crate, on hubby's lap, or mine, I always give the command off or come. Occasionally I do have to intice him with a treat.
Just give her some time to settle in. You've only had her a week. Teach her basic commands and it will make things easier. For the time being you might be able to use work-arounds like I am doing.
Good luck with her! She may just need a little patience.
