EBD Biting

Question
I have a 3yr old Female EBD. We have had her since she was 8 wks old. She is usually very mild mannered and not aggressive at all. Over the past few months she has been chasing my kids friends when they are over and biting their feet. I have enrolled her in obedience school but is there anything I can do to help her understand this is wrong. She does not do this to my kids or anyone in the family just visiting kids. I am afraid someone is going to end up getting hurt.  

Answer
Put the dog away when strange kids are in the house or outside with your kids. Avoid a situation where someone might get hurt. This is a territorial, protective thing she's developed as an adult. She loves her family but everyone else is a potential threat.
