Only one of mine gets really upset over them, she’s getting old now and it’s more just about being clingy as much as a big dog can be. The others don’t like it but they don’t panic like she does.
I just fret and fret about fires, I was grateful we had rain starting the Friday prior. I still watered some just to be sure hahahaha. When it’s drier out I waste water running my sprinklers once the popping starts.
I had a standard poodle who could hear a thunderstorm 60 minutes before it even got close to human sensory range. She would lightly whine and head into the walk-in closet.
Definitely not a gun dog.
