On edit: I just realized that I made a reddit hivemind joke in the vein of "I too something something OP's wife." I will work on breaking that habit. Baby steps!
I am surprised that neither of my dogs give a fuck about fireworks. They don't even tilt their ears towards 'em (and no, they aren't deaf). They will, however, absolutely lose their shit over sirens.
Yeah, my dog never used to care, then one year my ex-con redneck neighbor fired illegal mortars over the our, in a red flag fire zone, for house for 12 hours straight.
When I asked him to chill out, he threatened to kill me and said I hated freedom. Then then got in a physical fight with cops that night. Best neighbor ever.
