The most impressive beggars, however, get their own title: ‘metro dogs’. They rely on scraps of food from the daily commuters who travel the public transportation system. To do so, the dogs have learned to navigate the subway. They know stops by name, and integrate a number of specific stations into their territories.
The most interesting bit for me was learning that dogs can still breed with wolves, so they aren’t different species. Not mind blowing, really, but not something that would have occurred to me.
