When I first got the pup I noticed Buddy was not sure what to do when Chelse, which is the name I think were going with, would get to rough with the puppy teeth, Buddy would run and get out of harms way or sometimes get to pyysically rough thinking she's can take it.  After a yelp from the pup that scared Buddy, the last couple of days when he wants to put her in her place he turns his head and neck to the side and kinda forces or pins the pup to the ground just for a second or 2.    Not sure if thats how dogs show there dominants but I thought it was pretty neat

Buddy is doing exactly what an adult should do to show the puppy her behavior is out of line. Let him continue to teach her what not to do- too often people interfere with what's supposed to happen.

Mine either pin pups to the ground with a mouth to the pup's neck or step them down to the ground with their front feet - and you're right, it's fun to watch how the pack works

You absolutely should let the dogs work it out. Unless someone is bleeding profusely, leave them alone.
