Winston wakes at 5:30 every morning to pee. The only time he ever slept in was when he played until 3:00 am with his cousin ha ha.
Now keep in mind we have him trained to go back to sleep after he pees. Is what we do is quickly carry him to his pee pad, keep most of the lights off, talk really quietly to him and when he's done peeing, we carry him back to his crate beside our bed and he goes back to bed until about 6:30.
Unfortunately he won't sleep past 6:30 as that is his morning poop time and breakfast time.
