Mick is only a kid. He’s not ready to be trusted to behave if we left him loose in the house at night. A dog is a denning creature but a puppy needs to go there when his folks tell him to. So that he isn’t forced (he’d quickly learn to hate it) he gets to choose. I made it easy for Mick by rewarding each baby step with a tiny treat. As he walked into the crate I “captured” the behavior I wanted by saying, “Mick, Crate!” You’ll see later how he follows the command without argument.
