Yup, don't get too excited yet. It will take some time before she adjusts to you, and in this time it's important to do 3 things...
1. Establish routine. Make sure she's comfortable knowing about her new pack. How do you do this? Play with her often, for a given period, every day at the same time. If you are going to leave her in the house, or alone, take a very short trip (5 minutes, then 10, then 20) and come back. Little steps at a time, praise her if she's good when you come home. This lets her know you'll always return, and her being calm when you're gone is a good thing. Also, praise her lavishly at first. Let her know that good behavior is the way to please you.
2. Don't let her win. It's VERY important at first with a new dog to establish that challenges, even small ones, never result in her getting away with something you don't want. If she's playing, or tugging on a toy, or on the leash, never let the last action be you giving her the toy, control of the leash, or wandering off of a "stay" command. Let her know that you are the Alpha, always.
3. Work with her, every single day. Make her sit, praise her when she does. Put her on a "stay" command, hold your hand out to her to show her as you give the command, and walk away. If she stays, walk BACK TO HER, don't let her get up, and praise her. Keep doing this, for longer periods and with you moving farther away. Move to the outdoors to advance this. Keep doing it, but don't praise her if she gets up with out you releasing her (I use "ok" as a release). Then, work on "come" commands. You can do this from a "stay" command, and again praise her AS SHE IS COMING, so she understands that by going to you, she is doing the right thing. Work on this every day, for 10-20 minutes for the first few weeks. You'll be amazed how quickly they take to it, and it will really help with bonding.
Be patient, give her time, and have fun. Good luck.
