Bests & Worsts Reviews from Amazon

It did not stand up to my overly active puppy. If you have a strong and sizeable puppy, it will just bend and fold up. However that didn't matter because he loves it. Sometimes he allows it to stand up and he goes in and sleeps calmly inside. But sometimes it's just a great big toy that he gets hours of entertainment from. He dives upon the sides of it, crushing it, turning it on it's side, turns it into a small tight cave that he hides in, or chews on the edges. He growls at it and can entertain himself for extended periods of time. I'm saying it's not that sturdy and doesn't stand up strong to my puppy who was about 11 pounds at 8 weeks old and is over 20 pounds at 12 weeks old. But this little playpen sits in my kitchen and is so much fun for him, that it is worth every penny. I bought the bigger size that's upstairs in my bedroom and he sleeps happily in the larger one. This one is just like a fun-house for him. And yes, sometimes he calms down and sleeps in there.
