Murmuring at the moon

When I opened the door this morning, the moon was clearly visible and Zorro let out a couple of barks. But he's beginning to understand that he's not supposed to do that, even before I say "enough." He swallowed a yelp, and then he stopped.
He is energized by the morning moon, though. We dashed out the fence gate to the sidewalk. At first, he didn't want to go into the park, but a couple of women ran past us, and that was enough of a distraction, so off we went (fortunately, he doesn't try to herd runners). Down to the park, across the bridge, over to the tennis courts, and then in the other direction to the soccer field. Even though it was pretty humid and it stormed last night--prompting him to seek cover in the basement--he seemed unfazed and unafraid. Prozac? The waning gibbous moon? Who cares? It was a good run.
