Although my Min-Pin / Chihuahua is pretty much house trained, she still thinks the living room rug is a back-up toilet; so as long as I had to have a barrier, I wanted a nice one. This pet gate is beautifully made and needs absolutely no assembly. Each panel has these little "feet" that swivel out to maintain balance of the gate. I wish they had a two panel version for the other door to my living room. This costs a little more than some of the other gates, but it's definitely worth the price.
