Shocking Photos from 1915 Show How Much Dogs Have Changed

A shocking picture comparison of shows the disturbing changes many dogs have experienced due to mutation, cross-breeding and a desire for perfection which is putting dogs in danger. Caen Elegans writing in the Science and Dogs has shown how breeding and mutation has made dogs look entirely different from they were some years back.
Caen wrote: "The examples on the right are modern examples from multiple sources. 
 
"To be able to make an honest comparison, I’ve chosen pictures with similar poses and in a couple of cases flipped the picture to get them both aligned in the same direction. 
 
"I had to skip some breeds I wanted to include because of the lack of detail in the older photographs."
 
Bull Terrier
It seems incredible that at one time the Bull Terrier was a handsome, athletic dog. Somewhere along its journey to a mutated skull and thick abdomen the bull terrier also picked up a number of other maladies like supernumerary teeth and compulsive tail-chasing.
 
 
The Basset Hound 
The Basset Hound has gotten lower, has suffered changes to its rear leg structure, has excessive skin, vertebra problems, droopy eyes prone to entropion and ectropion and excessively large ears.
 
 
Boxer
A shorter face means a host of problems. The modern Boxer not only has a shorter face but the muzzle is slightly upturned. The boxer – like all bracecyphalic dogs – has difficulty controlling its temperature in hot weather, the inability to shed heat places limits on physical performance. It also has one of the highest cancer rates.
 
 
The English bulldog 
The English bulldog has come to symbolize all that is wrong with the dog fancy and not without good reason; they suffer from almost every possible disease. A 2004 survey by the Kennel Club found that they die at the median age of 6.25 years (n=180). There really is no such thing as a healthy bulldog. The bulldog’s monstrous proportions make them virtually incapable of mating or birthing without medical intervention.
 
The Dachshund
The Dachshund used to have functional legs and necks that made sense for their size. Backs and necks have gotten longer, chest jutted forward and legs have shrunk to such proportions that there is barely any clearance between the chest and floor. The dachschund has the highest risk of any breed for intervertebral disc disease which can result in paralysis; they are also prone to achondroplastic related pathologies, PRA and problems with their legs.
 
 
The German Shepherd Dog 
The German Shepherd Dog is also a breed that is routinely mentioned when people talk about ruined breeds; maybe because they used to be awesome. In Dogs of All Nations, the GSD is described as a medium-sized dog (25 kg /55 lb), this is a far cry from the angulated, barrel-chested, sloping back, ataxic, 85-pounders  (38 kg) we are used to seeing in the conformation ring. There was a time when the GSD could clear a 2.5 meter (8.5 ft) wall; that time is long gone.
 
 
The Pug 
The Pug is another extreme brachycephalic breed and it has all the problems associated with that trait – high blood pressure, heart problems, low oxygenation, difficulty breathing, tendency to overheat, dentition problems, and skin fold dermatitis. The highly desirable double-curl tail is actually a genetic defect, in more serious forms it leads to paralysis.
 
 
St. Bernard 
Once a noble working dog, the modern St. Bernard has been oversized, had its faced squished in, and bred for abundant skin. You will not see this type of dog working, they can’t handle it as they quickly overheat. The diseases include entropion, ectropion, Stockard’s paralysis, hemophilia, osteosarcoma, aphakia, fibrinogen deficiency.
 
 
"No dog breed has ever been improved by the capricious and arbitrary decision that a shorter/longer/flatter/bigger/smaller/curlier “whatever” is better.  Condemning a dog to a lifetime of suffering for the sake of looks is not an improvement; it is torture." Caen concludes
