dogs chewing up underwear

I'm not sure if this is the right board to post this on but has anyone else literally lost over $100 worth of underwear because their dog loves eating it!? I will take caution and close my doors and everything but some how some way if I look away for 10 minutes and a pair of my panties is on the floor my hound wastes no time. She always chews up my matching pairs that go with my bras too! It's bullshit and I have no idea how to stop it unless I make sure every time I take my underwear off I put it on an elevated surface.
