Over the years, pets have evolved from being a strange and wonderful distraction to an integral part of families all over the world. As human populations have grown, so too have pet populations, and with so many pets on the planet it’s fascinating to see just how this population is dispersed.

What drives certain countries to be so pet obsessed, while others are seemingly uninterested? Did you know that Brazilians love small dogs while Saudis prefer the bigger breeds?
