of course it is hard to see your babies fighting. what is really sad is they do not get over the fight. and they seem to want to fight to the death. unfortenly (sp) this has happened to me with mattie and gracie. and it was not a good outcome. your dog's will have to be kept separate forever and that is sad. I do not know what to tell you only you can make that choice. maybe there is a family member who would take one so you can still be close to him/her. good luck and maybe some one else can help you here.
