Members have answered this question already. Start training immediately. Do all the research your eyes can stand on this forum. Get yourself to classes ASAP or hire a private trainer to come to your home. Separate the dogs in the meantime and don't give Charlie anything he's going to want to bite your head off for until you learn how to control him.
