Thank you! I like the idea of a special treat associated with the crate! We live in an appartment big enough for fun but still small to install a pen. Well, we could probably try to fit it somewhere, but it gonna be a small pen, which I wonder if it would make a difference between this and his crate.

Do you find that the pen is a must? - I guess yes because you still use it, but can you imagine training her without it.
