Things have gone awry, though. When humans meddle in the business of hand picking the physical traits of dogs, sometimes things become downright unhealthy for the dog that is born. You want the perfect dog, but not at the expense of their comfort and health, right?
Here are some then and now shots of some of the most popular dog breeds. You really need to see what breeding has done.

THEN: Bull Terrier
This breed was first created in the 1800s as a mix of an old English Terrier and the Bulldog. This earlier version of the breed had a longer snout than the modern version.
NOW: Bull Terrier
Over decades of selective breeding, the Bull Terrier has developed a much thicker body and a considerably warped skull.
THEN: Saint Bernard
The original breed is thought to have been a descendant of Roman Asiatic dogs and had a much smaller skull than the modern version. It was a functional breed oftentimes used for work.
NOW: Saint Bernard
This dog isn't a work dog any longer. In fact, the breed has a large number of health issues that include a degenerative condition that affects the spinal cord (Stockard's paralysis), blood clot formations (hemophilia), and aphakia. Aphakia happens to be the absence of an eye's lens. They are also prone to overheating.
THEN: Pug
Pugs are thought to have been brought over by the Portuguese several hundred years ago and have subsequently been crossed with terrier breeds.
NOW: Pug
The modern Pug has to deal with a whole host of health problems due to selective-breeding. For example, they have considerable difficulty breathing and are known to have horrible cardiovascular health. Pugs also have problems with encephalitis (inflammation of the brain). Oh how breeding has caused problems for this fellow.
THEN: Basset Hound
Recognize this little guy? The main difference lies in the facial features. The older version of the Basset Hound had considerably shorter ears and a perky face.
NOW: Basset Hound
The modern version of the breed has a much droopier face, very long ears, and shorter legs. They are now known to have problems with their back and eyelids (eyelids turning outwards).
THEN: Boxer
Look at the longer snout that the boxer used to have. Rumor has it that the original boxer breed resulted from a cross of a Bulldog, Mastiff and Great Dane.
NOW: Boxer
Over successive breeding attempts, the snout has become much more compact. As a byproduct of cross-breeding, the modern Boxer has a high risk of developing cancer and lacks the ability to properly cool itself (not fun for the summer months).
THEN: Dachshund (Wiener Dog)
The older version of the breed had legs for days! Wow, those legs have really disappeared over the years.
NOW: Dachshund
Humans have aimed to create a different version of the Dachshund, with a much longer back and shorter legs. They get around surprisingly well for having those legs!
THEN: Bulldog
Notice the smaller head on the older Bulldog.
NOW: Bulldog
The original purpose of the breed was to bait bulls for blood sport. As a result, Bulldogs have developed much stronger and thicker bodies as well as giant heads. The modern Bulldog is known to be quite gassy and has a limited lifespan (sometimes less than 10 years).
THEN: German Shepherd
The original version of this breed had a longer, slimmer torso. This breed was created in the 1850s for the purposes of herding sheep.
NOW: German Shepherd
Notice the shorter, more compact abdomen on the modern German Shepherd.
