The barking and being crazy is just a part of them being young, but at an intensified level due to the fact that she missed that stage of learning the do's and don'ts from her mom and brothers and sisters. Now it's just up to you to pick up the slack of the mommy and her siblings. It's hard, but you'll get through it. I too got my Bella before that stage at only 8wks old, so I had to be the one to show her "NO BITING!" and tap her on her nose, or yelp the way that puppies would do it and then move her away and get up and walk away to show her I had no interest in playing with her any more. As far as the barking goes i would just clap my hands once to startle her and then say QUIET or SHHH while putting my finger to my mouth. She's doing really well now at 5 months but it is lots of work. Good luck, and just remember it does get better!
