How Breeding Pedigree DOGS has Changed in 100 years ?

There is an opinion that purebred bred dogs have special properties and generally look more beautiful. But recently on the Internet there were photos from the book of 1915, V.E. Mason “Breeds Of All Nations” (Breeds Of All Nations by WE Mason) clearly demonstrates.

How in the last century the species of all known breeds of dogs has changed. It is clearly seen how the age-old selection work on the “improvement” of rocks adversely affected the appearance and health of thoroughbred dogs.


The modern boxer now has even more problems with overheating due to the fact that the muzzle has become even shorter and more upturned than before. Shortening the muzzle, for example, leads to problems with teeth and hearing. A lot of puppies are born deaf in one or both ears. Often there is an entropion (the turn of the century). There are several more disorders associated with the preservation of their appearance – aortic stenosis and arrhythmogenic cardiomyopathy of the right ventricle, hypothyroidism and bloating.
