i got my pup when he was 9 weeks old. we used an airline crate
for a few weeks. then he was in a crate that could house a full
grown Great Dan. he was fine in the large crate. i didn't use any dividers.
i wouldn't cover a crate. i'm afraid the pup might pull whatever the crate
is covered with into the crate and harm himself. i don't lean anything
on the crate and nothing is laid on top of the crate. i make sure the
crate is in a position where the pup can't come in contact with anything.
i never put my dog in his crate with his collar on.
