Advice for Training Abused or Neglected Rescue Dogs

I recently got an e-mail from a friend who was asking for help for her rescued pit bull. Here's an excerpt from the e-mail (edited for privacy): "Hey Amber, I have a 1 year old pit bull. I've had her for 6 months. She came from a horrible situation. She was bred to fight (although I don't think she ever did), and was abandoned with two other pits and some cats in a north side house for a month with no food and only toilet water. She was bone-skinny when I got her (she was only at the rescue for 2 days), and she had mange and open sores all over her body." My friend is now looking to socialize this dog, and teach her some basic obedience so as to make her more adoptable. Currently, the dog has issues with people, especially men, that my friend believes (quite correctly) are because of fear issues. Apparently, she is also fearful out in public...a sure sign of bad socialization. (Click post title to read more.)
