I was reading the other thread and you got a lot of good advice over there. Socialization is the key right now. Lots of people and kids and dogs and cats and anything you can think of. Take her everywhere with you. Being so young, she will have missed a few things from her mother but you can start teaching them to her, like not to bite hard.

Also start her training at home right now until you can get experienced trainer or puppy classes. Train everyday, turn playing into a training experience and exercise. She's a little young for long walks but as she grows walk her all the time. Also consider getting a crate, there are usually crates on craigslist cheap.

My pitmix was my first one and he is an absolute delight. Smart, easy to train and a social butterfly.
