What is this thing they call a doghouse?

Last night Pat and I took Churry to PetSmart to pick out a new bone.  While we were there we looked at lots of things, her favorite being the birds.  She was very fascinated by them, much like the fish at Bass Pro Shop or Cabella's.  After we watched the birds and a hamster we walked around the store practicing Leave it's, Sits, etc.  We walked by some doghouses and I realized she has likely never been in a tight enclosed space like that.  We have a large wire crate for her.  Her travel crate is solid walls, but it is pretty big and she hasn't used it for several months.  This doghouse was also up a bit on a low shelf so she had to jump up to get in it.  She thought it was great fun!  She went in and out of it for me several times.  Who knew being in the doghouse was so much fun!
