I have to agree. I don't know why dogs go nuts like that, I can't even leave my dog out of her crate when it's bedtime and she's tired, something about not being in the crate when it's sleep time makes her crazy :P And god forbid if I left her out of the crate even if I just ran to the store and back!! I can't imagine. But really, if he's crate trained then you're better off not throwing him off by suddenly taking away the crate, the crate has become his 'den' and I'm sure he wants it

I think once dogs are crate trained then it is forever so, hehe.
