Every man finds his best friend in a dog and this trend of keeping and domesticating dogs and the relationship between human and dog is running since 18,000 to 30,000 years. But as the time changes, we know everything at its place changes. In relation to it due to selective breeding the dog breeds also have changed. The revolution in dogs have made them totally indistinguishable and more disease prone.
The intensive breeding of dogs has revolutionised them into completely unique breed with quirky physical and mental traits. This series of pictures will let you more that how human's passion for generating the pooch has transformed few breeds into being almost indistinct. The change in dogs varies from their colour of eyes to its curve and size.
The English Bulldog is known to be the most changed dog compared from its ancestors. It has been endured to an extent where it carries almost every possible disease.
Earlier the Bull Terrier was created in the early 1800s with the mix of old English Terrier and the Bulldog. It had a slim body with curves and a more sculpted nose.
Over the years, the change in Bull Terrier has made him a stocky fighter with more warped skull and heavy abdomen. It has also gained an enthusiastic tail-chasing character.
Several years ago, Basset Hound possessed short, curvy legs which were the result of specific gene. They also carried diminished ears on their droopy face.
After so many years of breeding, now the Basset Hound's bellies are much depressing towards ground. Their rear legs also seem to be lower now along with the excessive skin on face and huge floppy ears. They have become more prone to vertebra disorders.
Boxers are the heirs of defunct bullenbaiser breeds. Prior to human's interruption, these dogs were designed as bull baiting dogs and were aimed to help butchers in controlling the cattle. They carried a longer face and longer earthward tail.
But now the boxers are transformed into working dogs. They entail a shorter face with a big mouth that slightly points towards upper side. But this change in them has hosted several problems and it is known that in hot weather these dogs are prone to cancer more.
Earlier the Dachshund used to have more operating legs and a neck more proportional to its size.
But by the grace of humans, today's dachshund carry stretched back and shrunken legs that makes it troublesome for them to maneuver over hurdles a few inches off the ground. These dogs are known to carry greater risk of paralysis.
The German Shepherd once had a thinner abdomen and the stance was more pointed than the one we realize today. To mutate this breed, the first try began in 1850s with the aim to preserve their traits.
Today's German shepherd is an outcome of too much of breeding that spoiled canine species. The dog is described as a medium-sized dog which is very far from 38 kg that we see in the conformation ring. Barrel-chested, sloping back are the today's shepherd characteristics.
Early Pugs were derivations of Chinese happy dogs that were brought by the Portuguese between 15th and 16th centuries. These were called Dutch mastiffs but later they were crossed with terriers and smaller dogs.
Modern-day pugs suffers from many health problems like blood pressure, heart problems, low oxygenation and many skin fold dermatitis. And the curled tail is a genetic malfunction that leads to paralysis.
