Like chickens, as far as pups are concerned when it is good and light it's time to get up.
This is the first real summer litter I have had (normally aim to have litters in teh winter for this very reason, as less likely to annoy the neighbours) and the little darlings have had me up as early as four. They aren't hungry, though Mum does give them a little eraly morning comfort. as she just doesn't seem inclined to refuse them.
They have a mad dash around for half an hour, and then go back to sleep, but by then they have the other dogs all up.
Pup will gradually get used to sleeping a little later once they ahve full bladder contril around five months.
Just make the morning session not that interesting, gie them a chew or comething, and perhaps keep the older one crated or take one of them to your rom in their crate.
