5.Bedlington terrier
The morphology of the bedlington terrier is undoubtedly one of the most striking.A similar resemblance to that of a sheep has been sought, which has culminated in an anomalous form of the skull.Photograph shows a copy of 1881 (left) that has nothing to do with the current one.
It is susceptible to various diseases, such as heart murmur, epiphora, retinal dysplasia, cataracts and a high incidence of kidney and liver problems .

Although the incidence of health problems is not as high as the boxer, for example, if it presents frequent problems such as epilepsy, deafness, thyroid problems and digestive dysfunctions among others.
12 German Shepherd
The German shepherd is, by far, one of the most battered races in beauty pageants.So much so that there are currently two types of German shepherd, the one of beauty and that of work, the first being the most affected, since the second still resembles the 1909 model that we see in the image.
Currently his main health problem is hip dysplasia , although it can also suffer from elbow dysplasia, digestive and ocular problems.The photograph that we show you is of the winner of a 2016 beauty contest, a dog that, probably, in a few years will not be able to walk through the deformation so large its column.Even so, the "current standard" requires German shepherd dogs to present this curvature, totally abnormal.

The cavalier king Charles spaniel is undoubtedly one of the most popular dogs in the UK.We can see part of the young king Carlos II in the photograph on the left, posing next to his favorite dog.The cavalier king Charles Spaniel was an exclusive dog of the nobility and the ladies used to put it on their skirts in winter so as not to go cold.The king Carlos was one of the first to start selecting specimens to achieve a concrete morphology and desired, based simply on the "beauty" of the dog.
William Youatt, a veterinarian specializing in diseases, was one of the first critics: " The breed of King Charles is currently materially altered to bad.The snout is very short, and the forehead is ugly and prominent, like that of the bulldog.The eye has twice its original size, and has an expression of stupidity with which the character of the dog corresponds exactly ."
Dr.William was not misled, act This breed is prone to many diseases, including hereditary disease syringomyelia, tremendously painful .They are also susceptible to mitral valve prolapse, retinal dysplasia or cataract heart failure.50% of dogs of this breed die of heart problems and the last cause of death is old age.
16.San Bernardo
The St.Bernard dog is one of the most famous bulldog dogs, perhaps because of its appearance in Beethoven , the well-known movie .In the photograph of the On the left we can see a less thick dog, with a smaller head and less marked features.

Like all the aforementioned races, it is susceptible to various diseases such as allergy, elbow dysplasia , hypothyroidism and other types of allergy .Their life expectancy is over 11 and 12 years.
Why do all these races suffer so many health problems?
Breed dogs, especially those of pedigree , have been crossed for generations between siblings, parents and children and even grandparents and granddaughters.It is a habitual or desirable practice, however, even some respected breeders include the crossing between grandparents and granddaughters.The reason is very simple: it seeks to enhance the attributes of the breed in addition to not to lose lineage in future puppies.
Information from the BBC Pedigree Dogs Exposed documentary has been used.
The consequences of inbreeding are evident, proof of this is the rejection so great that society experiences towards those who practice it.In ancient Egypt, specifically in the 18th dynasty, it showed that the royals who carried it out were more susceptible to perpetuating hereditary diseases, to aggravate existing hereditary diseases, mortality early and, finally, infertility.
As we have commented not all breeders carry out these practices, but they are common in some cases.For that reason it is highly recommended to inform us properly before taking a dog to our home, especially if we have thought about going to a breeder.
