As my small monster little darling sleeps in a crate in my bedroom [first dog ever to do so but at 3 weeks old and barely 400gm it was too risky to have her on my extra high bed], and doesn't actually go to bed until around 1:30am, it is not unusual for her not to ask to get up until midday - or later. I should add that she insists on the door of her crate being shut and the dohickey across it. It's her bed and even though it's in my bedroom, it's disturb her at my peril.
She knows when I finally go to bed [around 3am] and when I surface [late] in the morning - opens an eye then goes back to sleep. She's happy. I'm happy. And we just suit each other perfectly.
