Fear and aggression are both often due to underlying fear and/or anxiety. Working with a trainer will help you learn how to correct behaviors in a way that doesn't exacerbate anxiety or fear. It may be helpful to discuss anti-anxiety medication with your veterinarian as well. What you are describing is not normal, but working with behavior modification techniques and possibly with medication could be very helpful. Best of luck with him. https://www.petcoach.co/article/6-common-myths-about-dog-aggression/ https://www.aspca.org/pet-care/dog-care/common-dog-behavior-issues/aggression

    Thanks for using Petco Pet Education Center, formerly Petcoach! These types of behavior can certainly be improved. However, usually this requires in person dog training by a qualified dog trainer. For that reason, I recommend you consider seeking the help of a qualified dog trainer in your area who can work with you in person. Good luck and have a great day!
