We move, and pack this thing for the dog all the time. It’s easy to fold and fit into almost any space (we rented a dog friendly Airbnb and this was perfect from keeping our dog downstairs). We bought it originally to keep Coco out of living room during day. 
If you have a “more aggressive” or exploratory dog, they’d push right through it. Our little princess is too afraid too.  (She’s afraid of a half closed door.)
