I'm up and awake by 6am every day. Not out of choice. My dog just knows when it's walkies time, and reminds me of it with barking, licking, and throwing his lead at me.
Granted, I could change the time I walk him and he'd settle into a new routine, but tbh I like being up early and having things done. I now never skip breakfast either, and being woken up by the happiest, waggiest dog in the world, means I wake up in a good mood.
