How 100 Years Of Breeding Changed These Popular Dog Breeds


Improper breeding causes a lot of problems to the dogs. Below is the list of the most notorious changes in some popular breeds.

11The Bull Terrier

The Bull Terrier has changed a lot over the years due to seriously impaired breeding. While breeders think that they’re making these dogs look better, they don’t realize the amount of damage that they’re doing to the dog due the drastic change in appearance created by improper breeding.

These dogs often suffer from problems with their teeth. This is because they have too many teeth in their enlarged skulls. Improper breeding has also caused mental deficiencies: one is the dogs will often chase tails that are no longer there. This can be frustrating for the dog who just wants to see his tail. When he can’t find it he can get frustrated and that can lead him to acting out or becoming dangerous.

10The German Shepherd

The German Shepherd was considered to be a medium-sized dog and weighed about 55 pounds. Today, the German Shepherd is considered a large dog. Over the years breeding has made this dog a complete distortion of what he used to look like.
Today’s German Shepherds are 30 pounds heavier than their ancestors, they have sloping backs, extreme gait and a barrel chest. All of these changes have caused a variety of problems for many German Shepherds as they age. The most common issue is painful leg problems.

9The Pug

The Pug is a dog who is in high demand.  Over the years, this dog has been seriously genetically modified.
Unfortunately, he is the one who had to pay the price. This dog has been bred to exaggerate some of its traits, especially his curled tail. These tweaks in the breeding have made these dogs very susceptible to high blood pressure, low oxygen levels, breathing problems and a tendency to overheat. Also, dental problems, heart problems and dermatitis in the folds of their skin. While the curly tail is what makes people love these dogs, it’s actually a genetic defect which can cause the dog to become paralyzed with age.

8The Boxer

The boxer naturally has a pushed-in face. Over the years, breeders have tried to make their snouts even more pushed in, this is what people wanted in a boxer.
Unfortunately, the breed itself is paying the price for these changes. Today’s boxer has a shorter, upturned muzzle because of the changes.

The boxer is prone to breathing problems, and they have trouble controlling their body temperature. It’s not uncommon for a boxer to have serious limitations put on his physical abilities because he’s unable to control his body temperature.

7The Salukis

The Salukis, years ago, looked like your normal everyday dog. Over the years, breeding has changed the appearance of this dog greatly. The skeletal appearance of this dog has changed a lot over the years. The dog today has extremely long legs, a small head in a very wide body. The problem, with all the changes that have been made, makes these dogs prone to serious heart defects.

6The Dachshund

The dachshund is also known as the “hot dog” dog. These dogs always had short legs, but a century ago, their legs and necks were proportioned to their size. Today they have much longer backs, jutted chests and their legs are so short that their stomachs almost scrape on the ground when they walk. While these changes made them more attractive to buyers, they also cause problems: these dogs have a very high risk of intervertebral disk disease, which can lead to paralysis. They’re also prone to eye problems such as progressive retinal atrophy, leg problems and dwarfism related disorders. So many problems do not worth the slight changes in his body wanted by the public.

5The White Terrier

The white terrier was a very athletic, high functioning dog, with great instincts. Today after years of bad breeding this dog is not nearly as athletic, and due to the intentional stunting, the breed can no longer follow his instincts. While he makes a loyal family pet, he isn’t nearly the dog that he used to be.

4The Bearded Collie

Over the last century, the bearded collie has been seriously genetically messed with. He never had the long hair that goes down to the ground that he has today. This beautiful mane of fur has made him famous in dog shows and his breed is greatly in demand.
Unfortunately, this breed has had to suffer for the alterations they’ve been given. This dog is very prone to allergies, especially skin allergies.

3The Saint Bernard

The St. Bernard was a very useful dog. These dogs were taken into the cold mountains to find lost hikers and to help them return home. These dogs once carry kegs around their neck filled with something to warm up the people that he’s saved from the mountains. Today, thanks to altered breeding, these dogs are much larger than they used to be, also they have pushed in faces and a great deal of extra skin.
Sadly, these changes in the breed have made him prone to a variety of problems such as eye and eyelid issues, a spinal cord disorder called stokers paralysis and bleeding and clotting disorders. Also, the changes made in breeding make these dogs slobber more than most breeds of dog.

2The Basset Hound

The basset hound years ago didn’t have such short legs. They were short but nothing like they are today. Also, his ears weren’t nearly as long as they are today. Finally, there have been some serious changes in his eyes. Today’s basset hound has droopy eyes. Unfortunately, these changes have opened up a whole slew of problems for the breed. They have way too much skin which can lead to dermatitis in the folds, the droopy eyes can result in severe eye problems and their short legs can cause spinal problems.

1The English Bulldog

The English Bulldog breed has been changed through breeding over the years. In the last 100 years, breeding changed this popular dog for the worse. The major change was to make the dog larger. There have also been changes made over the years in his appearance that make him look scarier and because of this the entire breed has had to suffer.
Unfortunately, these changes during breeding have made the English bulldog the most unhealthy breed of dog. He lives on an average of just 6.25 years. He’s prone to developing just about every disease imaginable.
