This is a great gate, we have a few dogs ( a Lab, Chihuahua, etc, etc and the gate with the door keeps them where we want 
them to be, very easy to use and the door is very convenient. The material looks sturdy but I just recently purchased this gate. I didn't have to use the whole extension but is there if we need. I recommend this gate but I think is a little pricey.

This gate it’s still serving its purpose and had last A LOT OF USE keeping the dogs in one place, highly recommend it.
