My dog was doing fine with guns then my brother shout a firework at him now and Loud noise freaks him out. I have been working with him to try and fix this. I just take the gun out no shooting g around him and he goes and get under something to hideous he remembers what the gun does. I take him to a pond where we train with a 22 and get someone to shoot it wile we are playing fetch to try and let him make the association noise is fun. It seems to be makeover g it worse when I tell him to heal now be almost expects the noise he does not watch it is almost like he expects the shout now. Is there a better way to if this.
