I have to agree with Karen. Though it would be very upsetting for you to part with one of your beloved pets if things do not settle down think how upsetting the situation would be for your dogs living in a constant agressive situation. Would perhaps another family member be willing to take one of them on so you can still keep in contact? I really feel for you on this but the dogs welfare must come first. My mother has had a similar situation but with bitches, who can sometimes be worse that the males as bitches very rarely recognise submission as the males do. She is an old hand with dogs and has years of experience but still finds this a difficult situation and has to be on her toes constantly. Whatever you decide I wish you luck.
