This might sound silly, but as soon as he starts that mess yoke him and pin him on his back and set strattle of him. Holding his head down and scolding him at the same time. hold him down til he calms down and quits squirming. Let him up slowly and repeat when necessary.
I ain't ever done it, but if you really want to get serious, you could bite him on the ear when he's pinned down too. Ive heard of folks thats actually done that. LOL.
makes perfect sense really, when a non dominant male decides to bow up to the dominant male this is what the dominant dog will do to remind the youngster that he ain't the big boy on the yard.
