I agree with Sidhewlf--start taking her out on a long line--at least 20 feet in length. That way you have control but she has room to roam a bit, you could even let it drag along...but when you want her to come. pick it up, give the command and if she doesn't respond, gently give a tug and repeat ONCE, then reel her in but be sure to start praising like crazy as she advances towards you. With recall training, you need to start praising the second they begin to move torwards you and continue until they reach you. Also--use the happiest voice you can! so many times I see folks trying to recall and they use a stern voice, thinking the dog will know they mean business--all that does is make your dog think that they may have done something wrong or you are mad--of course they won't want to come. make her think its wonderful and exciting and fun! Wheee!

Do not let her off lead until she is doing well recalling, then you can work on it off-lead.
As hard as it is, do not chase her--simply turn and run the other way while calling her or just turn your back and ignore her. Gracie did this occasionally (and still does once in a while when she is feeling particularly sassy!) and I have found that turning and ignoring her works well--she wants the attention and "the game"--if I ignore her and turn my back, she will come to me to try for my attention--I continue to turn away until she has settled down and comes right to me, then I praise and reward! When she does get to you---you cannot discipline or yell--hard not to when you are frustrated from a game of "keep away"--but recall must always be positive--if they fear a neagative response, they will not come!
good luck!
