Yup, I go in at the first fight grab both by the scruff of the neck and pick them up. To make it clear that I am in charge and don't put up with it. But at nine weeks I would just pull him out and put him on food maybe add some suppliments. But I would do that before things get bad and you have to cull any dog.
Oh yea, that was the first thing to happen..... didnt phaze them at all. This was so supprising to us. Picked the aggrssing pup up by the scruff and he never let go of the other one. Had to pry him off.

?....These are curs not pits!
