History and Origins

Country of Origin: England

One of the ancient breed types, Mastiff-like dogs have been known in England since before Roman times having been brought to the UK by Phoenician traders. The conquering Romans were so impressed with these powerful fighting dogs that could best any of their own dogs that they adopted them and used to fight in the arenas and in the Colosseum. As they were the only tame animals to fight in the Colosseum where everything else was wild (such as lions), this is where it is said their name originated from (the Roman word ‘mansuetus’ means ‘tame’).

Over the centuries, the Mastiff was used as a powerful guard dog but also for wolf hunting, bear and bull baiting and dog fighting. When these heinous pursuits were banned in 1835, the future of the breed looked uncertain and by the end of the second World War, there were only 14 left in the UK. Thankfully enthusiasts who recognised the gentle and noble nature of the breed imported Mastiffs from the US and re-established the breed but they are still uncommon.
