try a long line, take a 10 or 12 foot piece of cotten rope and clip it to her collar, make the dog sit ant your side throw what ever out for the dog to retrieve ( not farther than the rope) and gently " reel it back to you and reward the heck out of the dog, works with getting them to " come" also, has worked for me and I've had everything from hounds to bird dogs to " entertainment only" dogs, good luck!
