18 Dog breeds 100 years ago and what they are like today thanks to selective breeding

Dogs have been accompanying us since ancient times. Not for nothing have they earned the motto of being man’s best friend. Since these four-legged animals have been with humans for more than 30 thousand years.

That is why these animals were domesticated to be and coexist among us. However, it is because of that that several canine breeds have been transformed over time. And all this is thanks to the method of selective breeding used.

For those who do not know it, this method is based on artificial breeding that is used in domestic animals (and even in plants) so that new and improved breeds can emerge, much more evolved than the original.

However, this has not always been something that brings a special benefit to animals. Since on many occasions, they even modify their physical structure for the welfare of man, regardless of the physical health of the animal, which is often spoiled by this fact.

But the truth is that with the arrival of the 20th century and technology, techniques have been improved and perfected little by little. And this has resulted in new methods of selective breeding being discovered, leaving not even a shadow of the original appearance of many of the most common breeds of dogs.
