00:00this is a very special species the dog species it didn't take birth really in
00:04the jungle it was born around us and because of us their principal
00:09relationship with man was based on availability of food near the man that's
00:14how the wolf came to man right the wolf had to run around and hunt and said no
00:19it's better to go near these people they eat and they throw the waste the awful
00:23the remains and I can have all that and I can just sit there and guard them and
00:27they seem to be happy with it it's a deal and the deal remained because even in
00:32cities and of course in villages man was still throwing around enough stuff for
00:36the dog to survive fast forward to the 1960s 70s 80s places like Europe Japan
00:45Canada US availability of waste in urban places reduced dramatically because of
00:52cleanliness and because of door-to-door collection of waste you don't have to
00:57pile it up somewhere and even if you are dumping the waste somewhere it is in a
01:01secured bin that dogs cannot enter that is how the trajectory of dog population
01:08responds to the trajectory of urbanization the more a place urbanizes the more the
01:16free-ranging dog population diminishes the stray dogs that is for the simple
01:21reason that there is no food for them to eat but does that mean that those places
01:25don't have dogs they do have dogs but as pets millions of dogs as pets
