I would definately make sure she is in a crate with a big fat bone or toy everytime you leave the house until she finishes teething. When you are home make sure to supervise her when out of the crate. When she starts misbehaving by chewing on your furniture again I would pick her up and put her in the crate again with a chew toy or bone. Maybe she will begin to understand what she can and can't chew on. Good luck!
