I purchased this pet pen for my 2 small dogs to sleep in. I chose this because my younger rescue dog lived in a small crate for his first 6 months and was very fearful of a smaller place to "crate train him. It took some convincing and patience to teach him that he can come in and out by leaving the gate opened all day-and that there are cozy pillows and blankets as well as lots of toys. Most importantly that his "big brother" would also sleep in there right next to him.
Now he is the first one in when I tell them to go nite nite. The pen is so easy to keep clean, I just take it apart and soak the panels in a storage bin. This is a great buy, I would recommend to everyone.
