This crate is huge and my Dane is able to be comfortably crated.  Wayfair had the best price I could find for a large dog crate.

Tip:  I lined the bottom of the crate with foam interlocking mats before adding the pan (which you must purchase separately).  The foam mat provides a cushion so the pan doesn't crack under the weight of a huge dog pressing plastic against wiring.  

I needed a friend to help me put the crate together because of it's huge size.  One person needs to hold the pieces together while the other inserts the pins, etc.  Directions weren't terribly clear but we figured it out after some trial and error.
