I've just bought a crate today for our puppy who comes home in just over a week. YAAAAAYY!!! I was really worried about whether a crate was the right thing to do, but all of your comments have convinced me it is! We weren't sure whether to get a pen or a crate, but as we have cats, decided to go for the option he'd feel most secure in.
I just hope our little boy is as comfortable in his as as yours is!! :-)
