Hello, I have a female german shepherd dog that's soon to be 9 months old. I adopted her when she was a month old and I am aware that it was a mistake. I live in the front of a street that is very noisy and crowded. my dog's name is Chloe, She was doing fine when she was 3 months old and took treats when I took her outside, I gave her basic obedience training and she was doing great. When she was 4 months old, I took her to a dog park, a few dogs there were aggressive and they often bullied Chloe because she would stick to me and would not leave my side, they would chase and her and she used to be afraid of the dogs so the dogs would just attack her, i stopped taking her at the dog park after that. I took her again to the dog park a few days ago, now she would attack other dogs, she is still afraid of them but doesn't seem to back out. I can't train her with other dogs because people don't seem to train their dogs and so their dogs are reactive as well, I don't know any person that has a big dog like mine and would allow to walk along with me and there are street dogs too that come and go independently. She often goes at the window and bark at anyone randomly, she barks when the house bell is rung. When I take her outside, she would bark at strangers that act like they're afraid of her, or randomly anyone that's passing by, or she would quickly pull herself back in a scared manner if someone even draws out a bag or does an action unfamiliar to her. She is so scared and alert that biscuit treats don't matter to her on the walk, she never takes a treat outside and that's another reason why I'm unable to train her. At the walk, she often stops and keeps her hands on my belly and it ends up hurting me or making my clothes dirty. she doesn't play much in the park and sits on the bench after a while. She would pick the ball that I throw and then when she comes back, she drops it in the way and there's no other toy that fetches her interest more than that. She is very scared and reactive outside, is anyone else out there that has gone through the same problem? What should I do? I have tried training her in every way possible but it. doesn't get better and I'm not ready to leave my dog. Please, help!
