Have you tried teaching her to walk backwards, this often makes them throw their legs back. Hold a treat at the end of her nose and gently push her back. Take it a step at a time and use the back command, she should soon pick it up. (Forgot to say, treat her as soon as she puts a foot back and gradually build from there)
I haven't got a husky, but there are a few on here that do, perhaps they can help you further.
