Oswin

I'm looking to train my Grey. She has previously known the step-up command, yet she is a biter. She also does not like being touched. I would really like some advice because I honestly don't have the first clue where to begin. I'm concerned about her well being and she seems rather lonley.... She's also rather quiet and anti-social for a grey. Can anybody offer me some advice? Maybe some links to supplies or articles? Thanks in advance ~
