Question aboutAdopted husky mix?

I adopted a husky from the pound about a week ago, she's really chill and is very obidient. She's spayed and is 4 years, and was not destructive until today. I'm staying the night at my sisters house and we left her alone in the garage four 2 hours max. Both times she destroyed something. Is she just getting comfortable or what? When I go back home will she be nornal again?
