How a century of dog breeding ruined these beautiful animals (6 pictures)

Watching how one hundred years of dog breeding “improvement” actually ruined perfectly beautiful, athletic, and useful dogs, turning them into a caricature of themselves full of health problems, is really sad. Just look at the deformation endured by the bull terrier above these lines.


Science of Dogs collected these old photos from Breeds of All Nations, a 1915 book by W.E. Mason, and then compared them to examples of modern pure breeds.
