Is your washer or dryer on when she is in there? Or she could have been in there amother time and she is scared of the noise they make. I have 3 poms 1 is not scared of anything but the other 2 are scared of alot of things. One of them has clostaphobia (spelling?) She could not be in closed places. But now I put all of them in a lg. cage together at night (so the don't pee in the house) and they love it. I didn't think they would do it but they just loved it
