I think labs are notorious chewers. I know mine is, and it just drives me nuts. Kenneled or supervised at all times. Hopefull this will end as the dog matures.

If you put her in a crate get a cloth muzzle so she canot shread. my lab does that too. Or got to the grocery or butcher store and get some knuckle bones for her to chew on.
