Carlson Pet Products Mini Tuffy Metal Pet Gate, 38" W x 18" H, Includes Small Pet Door, White

I put this gate at the bottom of our stairs, to deal with the issue we've had of him going upstairs and doing messes on the carpet. We tried an expandable wood gate, but our smart dachshund figured out a way to open it, much to our surprise. It was a pain because we had to consistently open and close the gate. This gate is good because we have it set up right on the first step, and are able to easily step over it. It is hard to find a gate less than 24" in height, and being a petite person, it makes it challenging. This gate fits the bill. I like how you can secure the gate easily, but then loosen the fit easily if we want to allow our dog upstairs. This gate does the trick.
