I have a Midwest portable pen I use for my dogs. I'm very satisfied with it. Very easy to set up and fold up. I have large dogs, so mine is heavier (not sure how much it weighs--the box is long gone. Of course the weight depends on the height and how large a play area you get. Do a search on-line for weights, heights and prices to get an idea. Just an FYI: Years ago we had a Bullmastiff who truly was just like a bull. When he wanted something there was no stopping him. He saw some geese coming down the road and just knocked the whole fence over (he never did hurt or catch the geese). I had it secured to the ground with a few tent stakes. From then on I added a LOT more tent stakes to secure it to the ground and also kept an eye on him, never letting him alone in the pen. Things were fine after that.
