When the Romans invaded Britain in 55BC they found the inhabitants already had a mastiff- type dog, huge and courageous and which defeated the Romans' own dogs in organised fights. The Romans took some of these mastiff types home with them and used them for fighting wild animals in the Coliseum.
The Mastiff, once known as the Old English Mastiff, was used as a guard dog, a gamekeepers' dog, a hunter of wolves, and for bear and bull baiting. He was also used in the fighting pits until this activity was outlawed in 1835. This threatened the breed's survival. A number of Mastiffs had been exported to the United States between the wars and by the end of World War II, just a single bitch, Nydia of Frithend remained in Britain. The dogs exported to the United States became the progenitors of fourteen Mastiffs who were in turn sent to Britain post-World War II to revive the breed.
Now, although they are still not numerous, they have their devotees who take on the challenge of achieving type and substance combined with soundness of movement.

The Working breed group
Over the centuries these dogs were selectively bred to become guards and search and rescue dogs. Arguably, the working group consists of some of the most heroic canines in the world, aiding humans in many walks of life, including the Boxer, Great Dane and St. Bernard. This group consists of the real specialists in their field who excel in their line of work.
Breed standard colours
Breed standard colour means that the colour is accepted within the breed standard and is a traditional and well-known colour in this breed.
Breed standard colours in this breed include:
- Apricot Fawn
'Other' means you consider your puppy to be a colour not currently known within the breed and one that does not appear on either the breed standard or non-breed standard list. In this instance you would be directed through our registrations process to contact a breed club and/or council to support you on identifying and correctly listing the new colour.
Non-breed standard colours
Non-breed standard colour means that the colour is not accepted within the breed standard and whilst some dogs within the breed may be this colour it is advised to only select a dog that fits within the breed standards for all points.
Colour is only one consideration when picking a breed or individual dog, health and temperament should always be a priority over colour.
Whether you’re thinking of buying a puppy, or breeding from your dog, it’s essential that you know what health issues may be found in your breed. To tackle these issues we advise that breeders use DNA tests, screening schemes and inbreeding coefficient calculators to help breed the healthiest dogs possible.
