I had a bomb-proof labrador (honestly, one could - and did- fire a 12-bore about a foot away) followed by a lab/border-collie cross, who was highly intelligent, but terrified of fireworks.
I was interested to see how current, nervy, mongrel terrier would cope tonight. Answer, he's sailed through it! This to my amazement actually. He is used to seeing huge firework displays in France for Bastille day - from inside a conservatory and at a safe distance - but, of course, they don't do Bonfire night. He trotted out for his evening walk as per usual and never turned a hair at the whistling, banging things!
