I am never surprised. Around here we get fireworks somewhere about once a month right through the year. Its a total pain and I would like to go out there with a grenade launcher and terrify them for a change.
Apart from medication or preparations to help the dog overcome its fears, don't forget to ensure your dog is identified by microchip or tattoo in case the worse happens and it gets frightened and runs off. I would also suggest checking your collar and tag just in case.
Thanks, I appreciate the sentiment, but when you have one dog who's terrified of even the sight of a hot air balloon in the sky half a mile away, another who bolts at the slightest rumbling/aircraft noise, and two moggies scared of their own shadows, you're prepared for anything!
Good post, though, for the unwary - there's always a few!
Good time to stock up on the feliway and doggy pheremones (DAP?). Although it seems like Kerosene would facing an expensive time trying to calm his bunch down.
