Years ago we had 2 cocker spaniel dogs from the same litter.
Gun dogs.
Nature or nurture? I don’t know.
What I do know is that fireworks never fussed them.
They’d lie, next to one another, sprawled out, on their sides (a sign of a very relaxed dog!) in front of the fire (when we had one and them) and not so much as twitch at the loud BANGS! 💥 outdoors. Such contented sisters. Our lovely roans.
My spaniel is completely unfazed too, he’s a blue roan so maybe the breed is relevant. Mind you, he can hear the fridge open from a mile away, and be there with his nose in it when you could have sworn he was fast asleep in a distant room.
