Summary of Dog Breeds: History of Dogs and Human




In the first place, do you know “when do human and dogs started to live together?”

Relics of the interment of human and a dog in the Paleolithic era about 12,000 years ago, was found in Northern Israel.

The bones of human and dogs have been found in all over the world including in Europe, Russia and the continent which later known as America.

Those bones were found mainly in West Asia. Thus it is estimated that the history of human and dogs can be traced from West Asia.


The trigger of the co-existence was that human started to use dogs in hunting. Because the human was not powerful enough in hunting animals as mankind was too fragile. Nonetheless they could use fires.

Thus, the people started to cooperate and live together.


It is also said that dogs were eating leftover meals. Therefore, the bonding between man and dogs were built in the villages.

Also, dogs were used as “protections pet” and food source when people faced with starvation.

Of course, this is back in the ancient era so it is hard to image about it.


Dogs have received foods from human and helped them, so they are both in good relationships.

Thus, the human has tried to tame dogs to fill their needs such as protection, hunting, and employment.


They have been in homage from old time, and they both earn benefits from each other.


Nowadays, the number of dog’s types is over 700 to 800.

In this article, we will classify the dogs by weight and introduce the recommended ones.


There is no standard weight for small, medium, and big digs. 

In contrast, there is a way to measure heights of dogs (measuring the height from ground to the back of a dog) yet, we will classify the dogs base on the size.  This makes easy for you to read the article.
