I was awake for quite a while trying to figure out what was going on. The trouble with dog alarms is the lack of specificity: the offending intruder could be anywhere on the seriousness continuum from an Armenian terrorist to a traveling tortoise (for some reason, tortoises really piss off dogs, and they do seem to migrate, squeezing under fences and generally proceeding in a straight line no matter what the deterrents).
By the time 6:30 a.m. rolled around, I had discovered nothing wrong with our property, but there was one outdoor dog still continuing to bark up a tirade. I did notice that a child's scooter had been left at the side of the street behind our house - not a location where I would expect a child to leave it (too dangerous - they ride on the interior streets, not the thoroughfares). So it's possible that we had some criminal mischief going on, people pilfering stuff from back yards, as that type of activity does plague this little city.
As for our dog alarm, she may yet justify her existence.
