She's new to the world, so everything is new and scary to her! Puppy kindergarten will help, socialize her every chance you get. Take her busy places, walk her beside busy streets, always reassuring her that things are okay, everything's fine ... when she is calm, praise her. You've a long way to go, but establishing NOW that you are the alpha will help both of you in the long run - especially with a husky, they grow so strong so quickly that you want to teach her as much as you can as soon as you can, then keep reinforcing!
