Every dog is different. Do whatever it takes so the dog doesn't stress, especially during a keep. When a dog is making noise, there's something wrong and he is stressing. Most dogs like to be around other dogs(as a pack) Even a single raised dog rather be around his master. When a dog live in a crate, he should only be in there when his master is not around.
Keeping a dog in a crate could be the worst mistake. But if using the crate the right way, it could be very beneficial during a keep.
