As they got older we purchased Midwest's Life Stages Folding Crates. It's a wire cage type crate and it includes a divider panel that gives us the ability to adjust the side of their sleeping area as they grew.

When you are crate training a puppy, you don't want the crate too be too big or the pup will soil in one section and sleep in another. So the Midwest Life Stages Folding Crates were perfect for us because we didn't have to continue buying larger sized crates as the Cairns grew bigger. We could have easily started Molly (our first Cairn) out using the Midwest Life Stages Folding Crate but we already had a plastic pet carrier, so we used it until she outgrew it.

The crate also has a removable, easy to clean plastic tray that you can pull out and clean if necessary. Since the Midwest Life Stages Crate is foldable, it's great to take on the road too if needed.

Both Molly and Jack's Midwest Life Stages Folding Crates measure at 36 inches long, 24 inches wide, and 37 inches high which is slightly too big for Molly and slightly too small for Jack. But it works fine. We have their crates sitting side by side in our master bedroom so even though they sleep separately from us, they still feel like part of the pack since they are in the same room.
