““Over the generations, we have bred and inbred our canine companions to the point of disease and deformity. One analysis of popular dog breeds turned up a total of 396 inherited diseases affecting the canines; each breed included in the analysis had been linked to at least four, and as many as seventy-seven, different hereditary afflictions… In some cases, these disorders are nasty side effects of a small gene pool, of generations of breeding related dogs or relying on just a few popular sires. In others, they’re due to intentional selection for the exaggerated physical traits prized by kennel clubs and dog show judges.””
