> Pups don't know that the old grumpy so and so isn't going to act like mummy did so do need to be supervised until they are accepted into the family.
Now this is where I have found having a multi generational canine family so invaluable when rearing puppies.
My pups do learn before they leave that other dogs do not react or tolerate whet Mum does.
they know that grumpy old Kizi will near on take their heads off if they go near her, Jozi although 10+ in years will tend to play rough games, Myka will mother them as she just loves puppies, and that Inka will poke them ;), and by and large by 6 weeks, Mum Lexi will leave puppy education to the others while she acts like a queen, it all being quite beneath her, except if one yelps when she will suddenly show her maternal side.
In the past the Grumpy one was Kizi's grandmother, the Mummsy one her mother, and she was the Queen who only did what was needed with her own pups.
