All of my dogs have been oblivious to fireworks, and a neighbor two doors down used to shoot off professional grade stuff a few times each year, worthy of a small town's show .... I could FEEL the percussion stuff sitting on my on my deck. I'd try that thundershirt thing mebbe.... good luck!
Give 'em better drugs along with the music.... Oooo... Ohhh.... Oh Wow
.
There's a SRV album that has a dog bark at the lead in to one of the songs. I don't speak dawg, but that bark used to ALWAYS set one of my previous Labs off... high alert mode
.
Good luck tonight!
