Argentina's capital of Buenos Aires has among the most pet owners per capita in the world. The country's rising passion for dogs has coincided with falling human fertility.

Even libertarian President Javier Milei moved into the government house not with a spouse and children, but with the English mastiffs that he calls his “four-legged children.” A growing tendency to treat dogs like kids is changing Buenos Aires.
