Well it does work as a staging cage, but my 55 pound full of energy rescue chewed the cage up. Yes, while at work he went through the metal cage and made the door look like something Salvador Dali made. I guess a normal dog would have issues trying to get out of this crate but not my rocket ship of a beast. Many patches now and it is still holding up but sooner or later he will end this unit's life. I have been looking at used armored cars thinking that could work. Having fun with it now so enjoy. OH, I would have given a 5 star but the door even brand new had alignment issues.
