I agree with DogHouseMom. Since we don't know where you live, you could probably check with your local animal shelter. They deal with re-socializing animals all the time. My grandmother had a pekinese that hated my sisters and me. My grandfather hated the dog because it would come after the three of us. He never had patience for the animal so he would put it in the basement whenever we came over. Finally my grandmother got rid of it.
I loved watching "The Dog Whisperer" show and I hope someone will be able to help you. Your family and the dogs will be much happier.
