Doggy Troubles

I have been trying hard to give our puppy a little bit more freedom but she just makes bad choice after bad choice. She was having trouble with training so we set up a leash so she would stay around the front entrance of the house and be able to go out and in as she pleased. This worked ok for a few days but the last few days she has been sneaking into my bedroom (only room with carpet in the house) which is beside the front door and doing her business on my carpet. In the morning she likes to come up in the bed and hang out with us but this morning she decided to chew a whole in my comforter....she's pushing her luck....I'm not sure what to do with here.
