Where are all the street dogs?

Last time we were here there were street dogs everywhere.  It seemed there was a sickly dog that chose a restaurant seating area as its home at every restaurant.   There was dog poop everywhere.  Every park had multiple homeless dogs.  Dogs slept right in the middle of the busy street or in doorways.  I can’t find out what happened to them, but they are few and far between now.  I haven’t stepped in dog poop even one time.  We see a lot dogs walked on a leash, but almost no strays.
