Any advice on moving out?

I'm an 18 year old college student, and I currently live at home with my mother. My problem is, I would very much so like to move out, and become independent without creating issues between my mother and I. She's very sensitive, has anxiety issues, and is a controlling person.

I was hoping to get some advice to help ease her into the thought of letting me go, and hopefully in a manner that she'll allow me to take my dog with me. He's been a big part of my life, and he has helped me overcome a lot of milestones, and obstacles in my path. If he can't be with me, I'll be lost.

Please help me.. Thanks for your time.
