That sounds just like what happened when I got Daphne! She was 6 months old, and would chew everything! We though she was just teething, but it lasted for months! We tried to confine her to the kitchen, but she'd scratch up the doors, so then we put chairs in front of the doors, and she chewed them up! She also chewed on everything she could find in the kitchen - including the phone cord! My mom said that we had to get rid of her - so I took charge.

First we brought her to the vet, and she said that Daphne had seperation anxiety (she got stressed out when we left her alone). So we got her a crate to keep her in when we were gone. That REALLY helped - I strongly suggest you get a crate. Also, you have to desensitize her when you leave, so it isn't a big deal. Like, don't say goodbye and pet her and baby talk to her. Just put her in the crate, give her a chew toy, and leave. Don't talk to her or anything. Then when you come home the same thing. Don't let her out right away when you come home, or pay much attention to her. When you do let her out, then don't act over excited.

Also, you have to give her lots of exercise. If possiable, walk her before you leave for school, and again in the afternoon. And play games with her. And if possiable, take her to obedience class. It really is worth it - you learn so much about bonding with your dog and getting her to listen to you in obedience school.

Good luck with your girl! I hope it works out!
