Oh no! Why now?!

Mia is 9 months old now, and she's never really chewed on any of our stuff... only on her toys or bones. Only one time a few months ago did she chew on a blanket (made a little hole).

But this past week we caught her chewing a hole in our area rug in the living room, and I'm at home today since I'm not feeling well, and I was in the computer room and Mia was in the living room... I thought she was sleeping. But I just went in there and she chewed off a whole corner of the area rug and exposed the inside and everything!!!! (I don't care about the area rug and was planning on getting rid of it before we move). I think she's swallowed most of it since I can't find the pieces!

Why would she all of a sudden start doing this? Is she THAT bored?!

Here's a picture of the damage. It's wet from her saliva and from me spraying Bitter Apple when I found her chewing on it.

I guess this goes to show that she can't be trusted out of the crate yet when she's alone for extended periods of time!
