Thank you suggestions! It's only Pierre & his brother that fight...Matilda is a mini frenchie and she tries to break it up by jumping in between them haha.  If they begin fighting around me (usually over food), I just walk away and let them do their thing because they're too strong for me.  If they fight when my boyfriend is there he picks one up and tries to stop it.  They are pretty fiesty...they've never seriously injured each-other but they have drawn some blood.  Last night for instance, when they began fighting my boyfriend picked up Peugeot by his leg to get him away and all I could think about was him hurting his leg (what a disaster that would be!).  Pierre is normally the alpha dog, he has a HUGE attitude, but his brother is bigger and usually dominates the fights.  Anyway, today I tried to socialize them a little bit before work.  They have been fine so far.  I put them all outside on their own and watched them.   They are normally outside all day while we work, but they have a doggie door into the garage where they love to hangout.  Once they come in the house, I see their hair go up and can tell something is gonna start.  We are trying to not give Pierre attention in front of the other two but it's so tough given the circumstances! My boyfriends back is killing him so tonight we are going to try to have all dogs sleep on the bed with us like normal...I'll keep you all posted.  Wish us luck!
