We have 2 wheaten terriers, who are crate trained. The transition to this new crate was seamless. It is a beautiful piece of furniture. They both fit comfortably, and can stand up too. The divider between them is made of bars, so they can see each other. It is not adjustable.  This is the medium size, with a Caribbean Rum top, and tempting turquoise paint. This piece comes assembled. There are instructions to take the paint smell away, please follow them. The piece is made to order, and seems to be a quality built product.
