AwesomeDog is 17 weeks and last night had us up at 2:40am and then twice more before morning. We didn't leave her as DS1 has exams this week and needs his sleep. She mostly wakes 5-6am with the odd lovely morning where she sleeps until nearly 6:30am. It appears to have no bearing whether she has one walk, two walks, no walks, short, long etc as to what she does.
She likes to sleep from 8-9pm and would go to bed then if we let her. She's not keen on last wee before bed as it's cold and dark

She's 17 weeks and a golden retriever.
