I have a 2 year old Rottweiler that's about 150 pounds. I put his dog bed inside the crate and once he was confident that the noise he heard when he put his foot down wasn't going to hurt him, he loves it! During the day, I leave the door open and he goes in to sleep. At night or when we go away, I shut the door and he never tries to get out.

It was a little tricky putting it together. I read the comments so assembled it close to where I was going to put it. I just needed some help clipping the sides in place on the bottom, but was able to do the rest on my own. Like most people, the box looked like it went through a war zone, but none of the pieces were missing, nor was the metal bent except 1 small corner. I wasn't strong enough to bend it back, but it didn't matter in the construction - only cosmetic. Great deal!
