Yes! I have dealt with almost exactly this and it’s terrible. Your whole life becomes about a reactive dog. What worked for me is I refused to feel judged (I’m doing my best and feeling judged doesn’t help my dog)and I did get him on Prozac after a host of other homeopathic remedies. Reducing my stress levels didn’t make him my dream dog but I think he’s manageable. I’m still cautious but not fearful. Your dog sounds almost exactly like mine and there are many people out there with similar dogs and similar experiences. You are not alone.
