Learn about the Mastiff
The original gentle protector
The Mastiff is today's version of Britain's very old, heavy guard dogs. In our family tree, its ancestors include the Ancient Molossers and the old British bandogs. The same family also led to the Bulldog, the Bull Terrier and other bulldog-and-terrier dogs. Tap a circle inside to keep digging.
