I love this, and I actually bought 2 of them.  It is great for my chihuahas.  The 2 of them love to snuggle in one together.  The other crate I bought for my JRT.  He fits in the small size perfectly.  However, he chewed threw the dowels and got out of the crate.  I would suggest making the dowels from metal instead of pressed wood.  Otherwise I love them.
