The puppy is roaming the halls of the private residence at night? Why isn’t little Bo crate trained? I have always had a dog; and never let a pup just roam, unattended at night (too much they came get into). So...why no crate?
Ok, PaMom started it. CrateGate!
My dogs LOVE their crates (or "dens"). When they get a treat or a nylabone, they run to their crates to gnaw on it. Of course, there is the problem that the younger dog prefers my Big Dog's crate to her own -- "No, Ruby, that's Shelley's crate!" and she'll slink back to hers. They're identical, except that Shelley has a sheepskin over her crate bed . . . but Ruby chews on the sheepskin so she can't have one. She does have a waterbed under her crate bed because otherwise she rubs the fur off her 'keel'.
I can't imagine having an active young dog without a crate.
