We bought this for our new Boston Terrier puppy in September.It is a blessing!!  It fits his little bed, toys, bowls and he seems to like it. We use it if we need to keep him in one area when we are cooking, cleaning, etc, and if we have to go out for a couple of hours. He also goes in the pen for naptime (just like a toddler). It also fits fairly well in our small space.I think this works very well for a small dog. One of the best purchases I have ever made (besides our puppy, of course).
