Thoughts on sleeping arrangements?

I recently adopted an adult lab mix. I have a second bedroom where he has his bed, toys, food and water. But I also have another bed for him in the living room because he will not go on the couch and will also not lay comfortably on the hardwood floors on the living room without a bed.

When I leave his bedroom door open at night, his movement at night wakes me up. I am a light sleeper and any noise can keep me up and make it impossible for me to go back to sleep. I close my own bedroom door but can still hear him at 2am and 4am in the hallway. Would it be cruel of me to keep his bedroom door closed at night? I’ve considered getting those loop ear plugs but I don’t want to block too much noise in case of an emergency. In short, am I an asshole for keeping him in his room until the morning for the sake of my sleep? Be honest but pls be gentle I’ve only had him for 3 weeks and I’m exhausted.
