reactivity

Has anyone had some issues with their basset being reactive towards strangers? my sweet girl is a year and 8 months old and has been struggling since she was a puppy with terrible anxiety and fearful reactiveness. we have gotten to the point of now needing prozac daily for her anxiety. she is VERY fearful of strangers and very reactive. she isn’t aggressive in any sense, but i feel that is she was put in a bad situation she could get snippy. we’ve tried at home training, i’ve done so much research to try and help her, and started on CBD but she is still incredibly reactive. i hate feeling like i’m failing her and need some help here. has anyone dealt with this in bassets? here is a cute pic of her 🤎
