This is incorrect.

Dogs don’t just survive, they thrive. In Romania the government resorted to mass killing of dogs because they bred so successfully. Also in poor countries and remote places where you wouldn’t expect there to be excess food for strays.

Dog ownership is very often slavery. The nature of the slavery is very explicit - the dog’s work is to sniff drugs all their life, or retrieve dead game, or guide people. In other cases you can read in this thread, a past owner has had a captive dog and abused them for who knows what reason.
