This cage is extremely well suited to your giant breed dog. We no longer feel guilty of having to cage our Great Dane when necessary as he has plenty of space to move around and can even stand up straight now without having to crouch down.  We are pretty sure he's much happier as well!  Putting it together required 2 people but it went quickly and just a work of caution you'll need a couple of people just to lift the box as it's VERY HEAVY!  lol
