Thanks for the great advice guys. I went out tonight and bought the both of them a bully stick (Reghan is chewing my fingers to death), I gave Roxie hers first (so she wouldn't feel left out). She decided she wanted both sticks and hid Reghan's!!

It was too cute. They are alot less angry and now they ignore eachother. Reghan is still shaking alot, but seems to calm down when Roxie is near. She also seems to be looking for her. I think Reghan is sleeping an awful lot, but I guess that a puppy thing.
Also, if anyone knows how to see if she has a fever please let me know. She was licking my face and her tounge seemed a little hot!
