English Mastiff 105

The English Mastiff, also referred to simply as a Mastiff, belongs to the Molosser breed type. It’s one of the most ancient dog breed types. The Molosser, its ancient ancestor, was a ferocious war dog that lived over 5,000 years ago. It likely originated in the mountains of Tibet and was also used as a guard dog and protector of herds and flocks.

The English Mastiff, Tibetan Mastiff, Saint Bernard, Dogue de Bordeaux, Rottweiler, and many other modern dog breeds and largest dog breeds share the Molosser ancestry. Throughout history, the Mastiff has been used as a guard dog, watchdog, and protector.

Although they still have a protective nature, the English Mastiff we know today is a gentle giant and is a far cry from their war dog ancestor. Although the first Mastiff club was formed in the United States in 1879, the American Kennel Club did not recognize the breed until 1885.
