as far as I know Maya and her litter where kept with their mother and father for the whole duration of whelping. I got Maya at 7.5 weeks (I figured 3 days would not have made much difference). They where kept mostly in the garden, where the breeder had turned his shed into a make shift den for the mother. There was also a separate area the pups couldn't get to, so mother could get some alone time.
Maya has always been very mouthy, but from a very early age she realised quickly how hard to bite, and how hard was too much. She also learned that she should not bite skin, and so now we have a bunch of pulled clothes. When she gets in a very playful mood, she wants to play and its either get bitten, put her in her crate, or play with her, thankfully this usually happens once or twice per day in the evening so we get a toy out and she has a good play with it, very nicely redirects her attention to the toy and not our hands.
As I say she is very good, even when she is being "Naughty" I can put my hand near her mouth and she knows not to bite, she would sooner go for clothing or an old rag very occasionally I will let her have a bite on my arm, as long as she keeps it soft, if she gets too excited, I tell her no and stop playing, and then go back with a toy.
