How old are your pups??? Bailey and Charlie are brothers too and they fight. They are about nine months old now and I can say that it has gotten MUCH better....I know how you feel...it used to scare me to death and sometimes it was VERy hard to pull them apart and one or both would end up bleeding. I do believe they will outgrow it....it's been a long time since baily and charlie got into a bad one....it does tear your nerves up though...hang in there!
