This dog crate is sturdy and VERY large. My mastiff really likes it. Although it is made of steel, I am not sure if it could hold a dedicated escape artist, because the hinges do not seem all that strong (my dog never tries to get out so I can't be sure). I appreciate having multiple doors to access the large space. While it takes up a lot of space, it is one of the nicest looking crates I have seen- and easy to clean. The pan on the bottom seems fragile, but hasn't been a problem for me. Overall, I am very happy with this purchase for my easy-going large breed dog.
