I bought this x-pen to use on our rescue dogs. I have a tiny toy poodle right now, so it makes for a safe spot for her to be in and still get a little exersize, without being in a crate.
  I have used x-pens before, but once I got my own home, I realized you can form the x-pen into two 2x2 little pens side by side, perfect for two small dogs that don't like each other. Or like each other too much, if ya know what I mean. The clasps are perfect for locking it up.
