Shelley, I had to have a double crate made specially for my three wheeler. I can search out the name if you want to go down that road. The man lives in Stafford.
You might also check with your local humane society animal shelter - the one here offers various classes (regular obedience plus good citizen plus plus) and you can take them at your own pace though I'm not sure how that works (I just got the notice).
I buy most of my toys online since the stores around here cater to the hunting dogs. Don't forget to check Amazon.com too - they have a wide selection.
The only reasons I would not crate little bs with big bs is
(1) I don't want any fighting so you would have to play that one by ear
(2) If the little one potties in the crate accidentally the big b has to suffer too.
But I only have 1 so thats all I could think of
