Training Dogs to Spot Rattlesnakes

Today I returned home to find three men standing on a neighbor's driveway. One was the owner with his small dog on a leash. It wasn't until I had parked in the garage that I saw a big snake on the driveway as well.

It turned out that the neighbor had hired two men to bring a large defanged rattlesnake with a bite guard affixed to its face to train his dog to respond. The rattlesnake's rattle was surprisingly loud, and the Doppler effect was pronounced. For the while that I watched the training, the dog initially seemed to ignore the snake intentionally, although it would stay close to the owner's legs. At some point we later heard the dog yelp with fear.

Another neighbor happened by with her dog and said she had done the same training. Her dog had yelped as well at times, but he was apparently now able to sniff rattlers and notify her.

A Happening on Old Nogales Highway

This morning, while traveling north toward the airport on Old Nogales Highway, I saw a young man in a light colored shirt waving his arms rather frantically on the east shoulder of the road. Uncertain what he was going to do, I began slowing down from 55 mph when he suddenly dashed across the road, a car or two in front of me.

Just then another guy came out of the scrub to the same point. He was also waving his arms to get people to slow down. Barefoot, he dashed across both lanes two or three cars behind me.

Next was a policeman hopping into a sheriff's SUV facing south on the east shoulder. When he flipped his lights on, I jammed on my brakes, allowing him tear into the southbound lane, surely in pursuit of the two jaywalkers, or jayrunners.

What was going on?
