BRIEF HISTORICAL SUMMARY

:
FCI
The Mastiff, perhaps not in exactly the form as we know it today, has been with us for many hundreds of years, and played its part in history since well before the Battle of Agincourt, in the early fifteenth century. Even then the Mastiff was known for his courage and guarding instincts. It is recorded that when the Romans invaded Britain they found a mastiff type dog already here, and were so impressed that they took some back to fight in the arenas of Rome. When the Normans came to Britain the mastiff type was so common that the French word dogue found its way into the English language.
The breed almost became extinct in Britain after the Second World War. Stock was then imported, and since that time the numerical strength and quality of the breed have taken an upsurge. Combining grandeur with good nature, he is an extremely large dog in both height and girth, broad and deep in body, full of substance, with large strong bones.
UKC
The giant Mastiff may have originated in Asia, but England has been considered its adopted country for nearly 2,000 years. The breed has a long history as a fighting dog, protector of the home, and for use against other animals and as a weapon in war. In America, the breed is now noted as a devoted family pet and may still serve as a protector mainly by its imposing size. The Mastiff was recognized by the United Kennel Club in 1948.
