While I lived in India I had an adopted dog. This looks like him, but this is not him:

These dogs are a common sight everywhere in India.  They are called Indian Pariah Dogs, or INdogs for short, and sadly, most Indians I’ve met seem quite unaware just how remarkable these creatures are.

First of all, many scientists believe they are the oldest breed of dog in the world.

Second, no matter how hard humans try to control their population, still the INdogs win in the end, and the INdog population always rises or falls in tune with the available resources.
