Angie, there are a lot of specifics you can do that will help - And I hope that others will jump in and post.
(cop out, from me, haha!)
A few quick tips, don't have that much time right now:
I took a look at your other posts. I see that you just got her, a few days ago, is 2 years old, and has never had any training. She sounds like a high-energy dog prone to being nervous. A bit of background about your new dog in your post will help people give you advice appropriate for your situation.
At this stage, keep all the training positive and rewarding. Don't expect too much from her. She will need a TON of excercise to burn off that hyper, nervous energy. Being let out in the back yard and going for a 30 minute walk is not enough.
Seriously, SERIOUSLY consider trying to work 2 to 3 hours of walks, fetch, play time and one-on-one training sessions A DAY. I know it is a lot, but you can break it up: 30 minutes in the morning, short sessions of obedience and fetch, a big walk in the evening, etc.
Sign up for classes, get her into rally or agility or tracking - she looks like she needs to have a job!
Is she crate trained? I would get a crate and start training her to it if she is not. For now, you can have the crate in the kitchen or some other area near the kitchen, and crate her when you are cooking, etc. She won't be able to bother you but will be with you and not feel left out. Or get a baby gate to keep her in another room - somewhere where she can see you and not feel left out.
If she has never been trained to anything, the concept of doing something for you is going to be foreign to her, don't get discouraged if at first she does not seem to want to do anything - her brain is confused about it. It will be a new level of interaction that she will need to figure out before you can even get a basic sit. I would do with her like people do with puppies: shape behaviours you want. Have treats in you pockets all the time, and when she is doing something you want, reward her! She is NOT nipping at your hands? Good dog! Here's a treat!
Sitting quietly in the kitchen? Good dog! Here's another treat!
Basically you want to show her and reward her for what you WANT, instead of trying to teach her what you don't want.
Another thing you can start working on once she understands basic commands is a "place" command. Teach her that in the kitchen, she needs to go to her place and stay there - like a mat in a corner, out of the way.
Good luck, she sounds like there is a lot of very good potential in her just waiting for some love and training to unlock and bring out!
