Oh wow.... I'm so sorry... I really feel for you. I went through the same thing with my CC. I socialized him a ton (took him out everywhere everyday) since the day we got him (at 2 months old). I spent hundreds on trying to train him and they all ended up telling me to put him down because it wasn't "sociallization or training problem, but a mental issue"... Remi was an angel up until 6 months when my bf left town for 3 months. Remi got protective over me with other men but even with training and proper socialization, he still hated men. Then, when my bf got back, Remi hated women. Now, Remi hated strangers and dominant and/or bully type dogs and it takes days for someone to not become a stranger anymore. He is not allowed in public because of his aggression and has snapped at a few people. He currently lives with an animal control officer (whom he snapped at) who is willing to try and curb his aggression... Im hoping she can do the trick because he is a beautiful dog and a sweetheart once he accepts you into the family.
