Firstly re-introducing them each day is extremely stressful for the pigs. It isnt going to work out if you keep on doing it. So, introduce them ONCE (unless blood is drawn in which case they will need to be separated) in a nuetral area. All of the behaviours that Bobby is doing are completely normal. He is just trying to be the top pig. As I touched on before, the only reason that one needs to separate the pair is if blood is drawn. If this were the case I would then try a buddy bath. Good Luck and Welcome to the forums!
