The immense physical variety of dogs makes them among the world’s most diverse species and likely the one with the greatest range in size. A Pomeranian, for example, might weigh 2 kilograms, while a Mastiff could tip the scale to 100. So, why is this? And what does a dog’s breed actually say about them? Kathleen Morrill Pirovich explores the dizzying diversity of dogs. [Directed by Anastasiia Falileieva, Studio Plastic Bag, narrated by Bethany Cutmore-Scott, music by Zakhar Bo].
