You still see it with strays today in places where stray dogs are common. The aggressive ones get chased off and have to scrounge for food if they don't get themselves killed. The quieter, friendly ones get food and shelter. You can usually tell the strays that were born on the street rather than made that way later, because they tend to not make any noise and mind their own business. If they're interested in you, they approach slowly instead of running right up to you.
