The Adjustable Barrier Pet Pen is a must have for pets. I didn’t know I was going to like it so much, but it has made dog life easier. I use it mainly in the home to put the dogs away when the family is out. The dogs sleep on an old, large toddler mattress. The picture here shows me using six panels of the eight. This pet pen makes it easy to adjust the size for different places. I can make it into a circle as well, it’s pretty easy. The thin metal stakes have hook at the top and attach the panels together. The stakes can also be hammered into the dirt if needed. Definitely best thing ever, highly suggest it for any with pets.
