I think folks have missed your post here, @jlj781
Chewing on "unauthorized" stuff is a puppy thing and most do grow out of it -- with leadership and guidance. Since she's only being left for a couple of hours, it's troublesome that she's eating the house inside that time frame. Do you suppose there's some separation anxiety issues here?
Have you tried tiring her out completely before leaving her? Nice long walk before you dash out the door.
Kenneling is not a bad thing. I used to think like you do -- that a dog wouldn't appreciate being "locked in a box" but when kenneling is done correctly, they love their little dens and go into them without being asked!
I would strongly suggest kenneling her in the appropriately sized kennel when leaving the house is the best course of action. (Kenneling -- among other things --protects your home AND the dog from harm) A wire kennel with a blanket draped on top will create a calming den atmosphere. If she's never been kenneled before, you'll need to take your time in introducing her to the kennel. You can leave a super safe chew toy in there --- but if she's eats her bedding -- no blankets or towels for now. She could swallow them and choke.
Think about it. How is being locked in a laundry room away from the "action zones" in the house (kitchen, living room, kids rooms) better than being in a snuggly kennel in the heart of the home? If I were a dog, I'd prefer the kennel. I know my dogs do! As we speak, they're both in their respective kennels behind me, snoring away.
