I am having a hard time deciding to keep or rehome the puppies.

My question is, is it harder to train the puppies since the mom would try to show the puppies that she is the leader?

and would all the puppies be equally happy? so none of the pups will feel left out, like the runt of the litter?

also I don't want to really take away the dad's and mom's pups if it will sadden them, it's their family.

I have owned the mom and dad and they are well balanced. but I have never delt with a family pack (mom + dad +pups) so I am not 100% sure if I should show the whole dog pack that I am the pack leader, even of all the pups and mom. would me showing all the dogs that I am the pack leader keep the dogs from dominating or leaving out the runt?

Money, time, exercise, and training for all the dogs are no problem to me.

I just want the whole dog family to live the happiest life they can.
so I would rehome the pups if they don't all fell equally happy together. I don't want the runt to fell left out or sad?

I don't reinforce any bad or sad behavior.

So do you think the whole family pack can all live equally happy together with training?
or will the mom always feel the need to be the pack leader because of the pups?

ANY HELP IS APPRECIATED even give me links to where I can read about keeping a whole family pack.
