Lots of good advice in this thread, so I can’t really say anything that isn’t already said.
My dog doesn’t seem to care about fireworks or the vacuum cleaner, so I’m thankfull for that.
I suspect it’s partly due to positive reinforcement with treats as above, and if I’m playing war games on the PC, he’s used to machine gun fire and tank blast sounds.
I have however, had to obscure the glass on the bottom part of my mirrored wardrobe, because he will quite happily start a fight with his own reflection, hahah.
That one took me a while to figure out, he’d be chiling on his own upstairs and all of a sudden I’d hear a lot of growling… I almost thought I had a haunted house for a while hahaha
