This fold-up pen has many uses for me - I have two small dogs, still puppies. I can easily take this to another location to provide a secure area for them, and use it in various ways around the house, such as blocking off a portion of the yard (they started digging in the veggie beds) or making a double-gate so I can easily go in and out of the yard gates while working in the yard without worrying about an escape. And of course it pins together securely to make a pen and has ground stakes to stabilize if needed.
