Opposite situation here. When my dogs, all Labrador Retrievers, hear the fireworks boom they think it is time to go hunting! Don't hear much booming going on though. In prior years the booming would start a few days before the 4th and on the 4th it was like a war going on around us. I have only heard a few booms so far. I think that is due to the poor economy. People just don't have the money to blow up.
