I am glad you asked this Liz!
I keep Keegan crated during the day. But I give her free roam at nite. She usually staying in the bedroom, but not too long ago, when I woke up there she had chewed up a rug that my mom just got me at Christmas! So she stayed in the crate for a couple nites. If she does that while I am sleepin I can't imagine what she would do when I am gone. I eventaully want to leave her out but I don't think she is ready. Nor do I think Kylie is either!
