I have a 8 week old chihuahua yorkie mix and this pen is perfect for her. However, the gate is not super heavy so if your using it in the house, she can easily move it, which she has. I need to find weights for it. But, it works great, perfect size and gives her room to play. It comes with 8 panels and that is a little big so i just folded two of the panels and zip tied it for now.
