I've been following the Gwen Bailey timetable which is final meal at 9pm and then bed at 11pm. Having said that mine sleeps most of the evening so don't think it makes much difference! Hopefully someone with more experience will be along shortly.
That sounds pretty good to me. We tended to let ours out for final wee at about 11 and then DH would get up at 6. We got both dogs in summer though and were living in Budapest and DH loved being up that early and would sit on terrace with coffee and enjoy the weaher! Winter would have been a different matter!
