Puggles and Fireworks

In celebration of July 4th I was debating whether to take Puggles with me to see fireworks so that he didnt have to be stuck inside by himself. A few people warned me that he would be frightened, nervous, and probably bark the whole time. Others told me that he might flip out and need to leave. After thinking about all of this I decided to take him with me anyway, and if he got upset we could go back to our apartment, since the fireworks were only a few blocks away.
When the fireworks started, I made sure to watch Puggles intently. At first there was no reaction. The boom of the fireworks didn't seem to phase him, which made me wonder-is he deaf? Once the fireworks really got going Puggles seemed to be watching eagerly. His ears and head would perk up and turn from side to side when there were a lot of fireworks. He was quite funny.
We took this as a sign that he liked fireworks.
