Got this crate since the largest crate we could purchase in a pet store was quickly outgrown by our 1 year old male great dane.  This is perfect for him, he can stand comfortably with room to spare over his head, the doors are tall enough that he can get in and out with out having to duck his back to avoid scraping it (which the other crate did).  2 door options so you can have options in a room since it is VERY large.  But knowing he can stand or lay in it comfortable is all we care about.  Purchasing a 2nd one now that our great dane has a new "little" sister...also a great dane.  This was also the cheapest place we found for this crate...the pet stores sell it but for much more and a ton of shipping cost...got free shipping with this!
