Miniature Wire Haired Dachshund (Bitch)

We have been having serious problems with one of our bitches for some time now. It all started last November when one of the adult dogs took a nip at one of her 8 week old pups during a socialisation session. She flew at him and in the fray to split them she got hold of my hand and I ended up in Hospital for 5 days. Since then she has gradually got worse by attacking our mini long several times because she barked then it continued to when a dog yelped she would attack either the mini long or another dog. I have been at the brunt of this and have had had many injuries the latest last week whilst we were away in the Caravan at the Leeds show. This ended with a nasty finger injury.
We have no option but to keep her segregated from all the other dogs because you cannot plan for every eventuality, its bad enough when something kicks off and I am around, I would hate to think what would happen if I or the OH were not around. We have spoken to numerous people including the breeder, Vets and other dachshund people and it appears that the only option that we have is to rehome her to a loving finalhome where she will be a lone dog and with someone who has experience of dachshunds. She shows no aggression to people just those that get caught up in spliting up the fights. In every other respect she is a loving, loyal bitch who has been an excellent show girl and produced a lovely litter of pups. We are at our wits end with her but she has no life and ours and our other dogs are not safe with her.
