Greg is a male...   I am afraid with the new one they might hurt each other.....   Are you sure they will stop fighting      Greg has been a loner for some years now,,,  they are very territorial..   I'm asking because you seem to know from handling a lot of pigs.. 
   

Your Dotty-dot,  She is cute and very brave...   She might be the leader of the pack...   I hope you play with her often...  all of them in fact..
