Need help for Coton with unpredictable behavior

I have a Coton, Abby who is a little more than 3 years old. I love her more than any other dog I’ve had. Unfortunately her behavior is unpredictable. She is perfect in every respect, except she is overprotective and barks, and goes “bizerk” when she feels threatened by outsiders. She can sense when someone is not a dog lover. My vet feels she may have PTSD as I did not get her til she was 4 months old. I did buy her from what I thought was a breeder. Turns out he was a puppy mill. By the time I found out, I was already in love with her. She has bitten a couple of people when she went bizerk. The vet put her on “doggy Prozac” and she does. Not have too many bizerk episodes. I live in a condo so I now have to keep her in a doggie stroller when taking her in and out of our building. It works pretty well. Wondering if anyone else has had this problem. If it gets to a point where I cannot keep her, she may be put down, which I would hate to see as most of the time she is precious! Help!
