What Today’s Favorite Dog Breeds Looked Like 100 Years Ago

Due to selective breeding, many of the dog breeds around today no longer look anything like what dogs used to look like. The process accelerated in the 20th century as more sophisticated methods of selective breeding were discovered, and modern medicine allowed for breeders to inspect dogs at the genetic level. As a result, the breeds that are around today are vastly different from their counterparts from 100 years ago. These images of dog breeds then and now provide clear evidence of the impact of selective breeding.
