According to records, the Tibetan mastiff has a history of 8 million to 13 million years, and since its first discovery in ancient times, there have been many mysterious stories about it. The earliest documentary record of the Tibetan mastiff comes from the travelogue of the famous world traveler Marco Polo, who came to China alone in 1257 AD and met Tibetans and "dogs from Tibet" for the first time in Sichuan Province.
Marco Polo commented on this large fierce dog, which is "as big as a donkey, galloping like a tiger, roaring like a lion, and looking like a grand", Marco Polo was also the first person in Western countries to have a "big dog from Tibet", after the end of the tour of China and brought Tibetan mastiffs into Europe, which was the first Tibetan mastiff to enter Europe. In 1820, Tibetan mastiffs were imported to the United States by King George IV, and this century they were introduced to Britain, but in small numbers. In 1986, the British Kennel Club awarded the dog a transitional breed standard, and the dog's support rate continued to rise.
In Marco Polo's travelogues, in all the historical records of the Tibetan mastiff, the natural strength and unforgettable image of the Tibetan mastiff in terms of body and spirit are praised, and its bark has always been described as a unique and very valuable feature of the breed. The Tibetan mastiff plays a very huge role in the long blood fusion of the world's dogs and is the ancestor of many of the world's largest dog breeds.
Famous ancient European canineologists such as Martin and Joat, Maigny, Beckman, Sieber, and Sturbel and Berland emphasized the Tibetan mastiff because they were attracted to the origin of the dog and its role in Tibetan culture. It has even been suggested that this dog is the ancestor of all large mountain dogs and Mastiff breeds.
Genghis Khan, in order to expand his territory and crack down on external troubles, began to train and train tibetan mastiff puppies when he was a few months old. Finally, the Tibetan mastiffs who had been trained at home were formed into a legion of 30,000 Tibetan mastiffs, during the Western Expedition. When the enemy army was unexpected, unprepared and unprepared for the Tibetan Mastiff Army, this Tibetan Mastiff Army rushed to the battlefield. Defeat the enemy army and make great achievements for Genghis Khan's western expedition.
This Tibetan mastiff army shocked the world, and also made the world know more about the Tibetan mastiff. However, the Tibetan mastiff is a dog after all, although well-trained, but after the attack can not all return to the team, and later some Tibetan mastiffs are scattered in Central Asia, Europe, today in Central Asia, Europe found Tibetan mastiff, it is likely that Genghis Khan into Europe when the Tibetan mastiff was left behind, became the ancestor of many dog breeds.
