How do i stop my dog from doing this please help shes a danger?

Your dog's instincts of protection are in full force. First, I would definitely call the police, file a report and sue the neighbors who obviously do NOT need to be responsible for anything. It will take a little while and a lot of reuring from you. There is no need to put this dog down. For what reason? All she needs is some guidance. She is losing hair because of stress, she is not sure now when you go out if that is gonna happen again. When you take her out, make sure that you are confident and not scared and looking around. What you are feeling goes down that lead and into the dog. Reure her as much as possible and have a friend bring a dog over that is not aggressive AT ALL, acutally not submissive either or your dog will take that energy and get confused. Bring a dog that she has played with a lot and is not scared of. You are gonna have to do a lot of one one one to reure her and get her back into society, so to speak, and not be scared. You are her protection and she is yours. She isn't sure she can protect you now. It's time for you to let her know that you will protect her no matter what happens. Love, love and more love and reurance that she is a good dog and the aggression problems with other dogs will lessen. They may never go away completely, but you can do your part by reuring her everyday that she will always have you and you will take care of her. Why would someone want you to put this dog down? That is just insane. It wasn't your dog attacking, it was the others. Your dog is just having a hard time dealing with a very vicious attack and will need time to trust other animals again. Bright Blessings and Good luck!
