What do you think of this?

My dog is absolutely terrified of fireworks/booms/tv gunshot sounds, she always has been. We’ve socialized her like crazy for her whole life so I’m confused as to how I could train my dog to not have anxiety? She even has a prescription for Xanax because once she starts panicking, she cannot calm herself down. We’ve tried every approach possible when dealing with her anxiety and we’ve concluded that it’s just a major part of her personality.

*I’m more curious about the “training a dog not to be nervous” not Fourth of July celebrations. Obviously that will never change*
