Dog Wallpaper Free Biography

Dogs are a kind of wolf. They were the first animals that people fed on purpose, earlier than sheep or cows or chickens. People have been taking care of dogs since about 13,000 BC, in the Stone Age, before the beginning of farming (and possibly much earlier; maybe as long as 100,000 years ago, before people left Africa). Most likely, dogs themselves began this relationship by hanging around people's campsites (there weren't any villages yet), trying to snatch some of their garbage to eat. At first, people must have tried to scare the dogs away. But after a while, some of them realized that the dogs ate rats, and also helped to clean up food garbage that drew flies and other insects. So campsites with dogs were cleaner and healthier than campsites without dogs. Fewer people got dysentery and died.
