Your pup might’ve looked a whole lot different in 1900, thanks to generations of breeding.
The Pekingese has undergone perhaps the most significant changes in the past 100 years. The modern Pekingese is almost entirely fur; you can’t make out its legs because they’re so much shorter, their faces are flatter, and these pups used to have shorter, controlled fur. On the bright side, if you buy a Pekingese, you don’t need a broom!
The English bulldog has become stockier in the past century. Its nose is less pronounced, but you certainly can’t say the same for its skin wrinkles and rolls. The modern English bulldog suffers from a lot of breathing and overheating problems because of the way it has been bred.
This show dog wasn’t always as meticulously groomed as it is today. Generations ago, long-haired poodles had tighter curls, shorter snouts, smaller chests, and shorter legs. Now, they’re bred to look more “regal,” standing tall and proud with oftentimes very strange haircuts. Dogs are also bred for intelligence as well as physical appearance.
What was once a spry working dog is now a fluffy lapdog, thanks to breeding. The Saint Bernard has developed thicker and longer fur over the years, and its tail has fallen. They are bred to be much larger and their faces flatter than in past generations.
This herding dog has changed significantly over time. Their median size has increased (they can grow up to 95 pounds!), their fur has become longer and thicker, and their hindquarters are lower. German Shepherds are prone to hip dysplasia because of the way they have been bred.
The Brussels Griffin, or Griffin Bruxellois, has developed shorter legs over time. While some would say its cuter now, the older generations of the breed had pointy ears, a narrower gait, and less fur.
