Super-Dog

I was dog-sitting this afternoon, about 40 miles North of Pasadena, when I became witness to an incredible phenomenon. It's common enough, but this is the first time I've seen it in person.
   I was watching TV, with the dogs laying on the floor in the living room, when one of them grumbled, then she sat up and barked loudly. This dog almost never barks, at least not when I've been dog-sitting. She whined to get out, and when she was in the back yard she barked some more and then looked in every direction, like there was something to see that she was missing.
   My first thought was 'earthquake' but I didn't feel anything, and nothing in the house was moving or swaying.
   Fast forward to a few hours later, when I made it back to my place. I turned on the news, and I found out there had been a huge earthquake in Mexico, 7.2 (this is really big). Guess when that earthquake rumbled? 3:40 PM, right when the doggies started barking.
   Amazing. Incredible. The coolest thing I've seen in a long time, and I didn't even know what was going on at the time. The dogs heard/felt/sensed the earthquake hundreds of miles away, and knew enough to realize that it was something they needed to tell me about. Just... astonishing. Like you needed another reason to love dogs.
