Thank you for your replies, everyone.

We used to let her roam the garage when it was raining or cold outside, but the last two times she was in there, she tore the place up... It was strange because she'd never done anything like that before. I suppose she was taking her frustration out on our furniture.

I started letting her in the house during the day, but she's so curious about everything and she tries to knock over the trash. She used to repsond to a frim NO or a clap of the hands, but she's gotten stubborn and reckless lately, probably due to the chain. Any suggestions for discipline? I already know never to hit her, and I wouldn't want to anyway. I've had many dogs before her, she's just the most unruly. Yet still very sweet and loving.

Her name is Mirage, by the way, so we don't have keep referring her to only "she."
