I have this crate
PetEdge: MidWest Life Stages Double-Door Folding Crates and this ex-pen
PetEdge: MidWest Gold Exercise Pens w/Door
I used the crate to house break and crate train morgan. I used the divider to make the crate smaller so that she only had enough room to stand up, turn around, and lay down in. She had a nice comfy bed in there and a water bottle attached to the side. as she got better about holding it i gradually would make the crate space bigger until she had the whole thing. Then she graduated to the full ex-pen.
