Commuting to Work?

We have seen many dogs. The first one was the one sniffing our companion's purse. she was trained to sniff out contraband fruit. It was so endearing to see this sweet-looking black lab gently wandering around the baggage, quietly touching suitcases, then moving on. Then she stopped, kept her nose on the purse, and started wagging her tail. It was SO unthreatening, yet so efficient.
Outside the airport we saw the first of the many paired dogs that people walk on a leash. They usually are cocker spaniel types, with a few Dachshunds, poodles, and maybe a yippy dog or two.
On many street corners here in Santiago, there are dogs. They are homeless. There are no dog pounds or animal control officers or animal shelters. These dogs, for the most part, look pretty much the same. A few are different. They are very tame. For the most part, they are ignored by the passersby. They are not healthy (worms, ticks, fleas, etc.) but look good. One day as we waited for our bus, the doors of another bus opened and out walked a dog! He seemed to know exactly what he was doing. He came over to the bus stop, waited a few minutes, then started toward the next bus! Unfortunately, it didnt stop, and he looked just a little puzzled, like he was going to be late for work. On the corner just outside temple square there are three dogs. They have taken it upon themselves to control traffic. When the light changes, they gang up on a car and escort it around the corner till it takes up speed. Then they stand right in front of the car waiting for the red light to change. They bark, just daring it to start before they give it permission. As soon as the light changes, they move out of the way with a loud warning to behave!
