Title: A puppy can easily climb out of this
Review: It took my 4 month old pug about 10 minutes to figure out how to climb out of the pen, so I had to return this. I wouldn't recommend this for active and curious dogs. The only other negative is that the latches on the door were very small and hard to open. In terms of the structure, the pen is built of a sturdy plastic which is nice. Also it easily collapses so it's not a problem to move the pen around.
