My dog looks happy here, but he's actually trembling, and extremely anxious. The first firecrackers have just gone off in the neighbor's yard. He freaks out, scurries up to me, crawls into the hole I'm digging for a viburnum. A few times in years past, he's run away in fright, I've had to wait for phone calls, from rescuers miles away. It's the same thing with thunder.
