You did the right things when you got home, and now you know.
We know to not go out when there are going to be fireworks but we can't always be home for thunderstorms. The very best thing I have found for our thunderphobic greyhounds is the canine lullaby cd. They will start calming within a couple of minutes of the cd starting and you can see their breathing slow down, the panting stop and they lay down and go to sleep. This cd is priceless to me, so much so that I ordered a back-up just in case. When thunderstorms are forecast and I must leave the house I put the cd on for them instead of their usual radio station.
