How did dog breeds over 100 years
Unfortunately, the editors of Factroy were able to state only the fact that centuries of breeding for “improvement” of breeds is quite detrimental to the appearance and health of dogs.
The bull Terrier was a handsome sporting dog. Without the ugly faces, and saggy belly. New skull shape led to the emergence of dental problems and progressive deafness. In addition, the dog bull Terrier congenital dislocation of the elbow and frequent sunburns.
The comparison shows that dogs of the breed Basset hound are much lower, and their ears much lengthened in comparison with the dog in the Photographs of a century ago. From reducing back legs dog Basset hound got even more problems with the spine, and dysplasia of the hip. Because of this, pet is rapidly gaining weight, which only exacerbated his illness. Permanent eye problems from glaucoma to entropii (“cherry eye”). Maybe big ears and look cute, but the dog they bring great inconvenience.
Modern boxer now has even more problems with overheating due to the fact that the face became even shorter and more turned up than before. The shortening of the muzzle of prevadid problems with teeth and hearing. Many puppies of boxer breed are born deaf in one or both ears. Often entropion (volvulus century). There are several disorders related to maintaining their appearance, aortic stenosis and arrhythmogenic right ventricular cardiomyopathy, hypothyroidism and bloating.
English bulldog — star safety advertising posters of times of Churchill — he was a monster through breeding. Today is one of the biggest breeds of dogs. Actually there is no such thing as a healthy bulldog: canine hip dysplasia, congenital dislocation of elbow, hypoplasia of trachea, dermatitis of skin folds, brachycephalic syndrome, entropion… keep rocks made it impossible to give birth without medical intervention. Life expectancy — total of 6.25 years.
Even the German shepherd, which often was the standard “real” dogs, degrades. In the book “Breeds of all Nations” describes the standard 25-30 kg. Today it is much potjazhelevshie dog. This leads me to problems with the spine and hind legs. Elbow dysplasia and hip joint, intervertebral disc disease, lameness. As well as diabetes, cataracts and various tumors.
When dogs breed German shepherd were able to take the barriers with a height of 2.6 meters, but now the croup is lowered, the dog became angular, and the chest sticks out of the wheel, respectively, the German shepherd has no such physical indicators.
Pugs received a gift from man tail, which is twice more twisted than before, which, according to Musculus, can lead to paralysis. A shortened snout and wrinkled skin often lead to overheating.
Dogs pugs, like all brachycephalic have a huge problem with breathing and a predisposition to respiratory disease. Shortened snout always leads to dental problems and infections of the skin folds on the face. They are characterized by obesity. Pug encephalitis is a genetic disorder. The symptoms of the illness — convulsions, disorientation, blindness, coma and death. However, pugs can suffer from epilepsy that is not associated with encephalitis.
The Saint Bernard
The strongest changes were dogs Saint Bernard: once downed, athletic breed now has many problems with overheating and are more prone to various diseases. St. Bernard greatly added to the weight. The same elbow dysplasia and hip replacement, patellar luxation, bloating. It is often congenital deafness and epilepsy. In addition, breeders are heavily built up on his skin. Because of this, the dogs quickly overheat. With all the ensuing consequences. And cataract, “cherry eye”, eversion and inversion of the century.
Pictures dogs dachshunds show how severely disturbed the proportions of the legs and body of the animal compared to last, which means more risk and exposure to diseases of the intervertebral discs. Have taxes decreased hind leg that immediately gives problems with legs and spine. Dachshund dogs were faster to gain weight. Problems with the intervertebral disks can make the dog cripple.
Caroline kisko, Secretary the kennel Club, UK: “Breeding work with dogs is a relatively unregulated industry, and, along with every responsible breeder, displaying healthy animals, there are always those who raise dogs for money and try to strengthen some characteristics of rocks, appropriate fashion and in demand. They often ignore the rules relating to the health of dogs in the breed standards, and all other criteria.
Puppy buyers should always see not only the puppy, but his parents, and avoid those dogs, the parents of which observed any exaggerated properties — for example, excessively short muzzle, excessively wrinkled skin or overweight”.
