History It is said that the Old English Mastiff may have been introduced into Britain by Phoenician traders. It is sure that they have been used as war dog by the Roman legions though. The Mastiff has been used as war dogs until the late middle Ages. After this they have been used to hunt bears and wolves. The breed’s popularity declined in England during the 19th century, but they remained fairly popular in the United States after that and were used as guard and companion dogs.


The mastiff is a massive dog, and they are also very powerful. Mastiffs are one of the heaviest dog breeds that there is. They have a very dominant demeanor. These dogs are fearless, and have a lot of courage. They are often referred to as “gentle giants” and they are a good combination between radiance and dignity.
