We ordered this pet pen for our 15-year-old Shih-Tzu mix, who has a hard time navagating through the house due to vision loss, and often gets stuck in corners. When we need a few minutes to do things, like make dinner, she goes into her pen and has ample room to wander about without her or us worrying that she'll get stuck somewhere. It's big enough to fit a comfy bed so she can lie down when she gets tired. It's easy enough to move around, and we can store the pen easily by making it into a square pen and storing the extra panels inside the square.
