New Dog great, but wont let us near her

Question
We have an 8 month old Baenji/Lab mix, Spartan. He has been a great dog so far, but has become a bit aggressive (wants to play to much) with other dogs. We adopted Autumn, (2 yr old, Border Collie/Lab mix) sunday 10/14. She is so shy. When she is on the leash, she is almost more trusting. She and Spartan have already really hit it off. He was very aggressive with her immediately, she growled and nipped and now it's not as much, he's already learned his place. She follows him around, lays down near him (not touching). We have two kennels, she goes in either and he just uses the other... he's been verrrry accommodating to her. She follows him around.

Problem is she won't let us near her. If we are playing with Spartan, petting, etc., she might come up, kiss, nose us, might let us pet her, but lots of times jumps away. She starts at loud and not even very loud noises and paces around our kitchen table (has extended now to the rest of the downstairs), nonstop.

Any advice??? I don't think Spartans the issue, I think she just may need time and love. She is a rescue dog. She was rescued at 3 months old from a house with 40 dogs and has been in and out of foster since. At her last foster care, she played with other dogs and even encouraged an older dog to play.

Any advice would be great. You can even see her on dogster.com, Autumn, Salinas, CA (93907)

Answer
Well what often works is to offer her a tiny treat,and for a few times don't touch just let her take it from you,then slowly reach out to her,even if it's only for a second

Also it may take her a couple weeks for her to get adjusted to the new environment,it sometimes takes up to a month for them to settle in,although two weeks is the average
