We just got 2 puppies and needed a palce in the yard for them to play.   Since they're going to get big we went with the 40" tall panels and got 2 kits to make a 10x10 enclosure.  This gave us 2 gate and we added a baby pool for them.   It was ez to install and very flexible with the design.    It's sturdy and portable making it ideal for camping.
