Mastiff
Background
The history of the Mastiff (also known as the English Mastiff or Old English Mastiff) is extensive. They are similar in size and build to dogs that were carved into figurines as far back as 6th century BC. Although we can only speculate on the breeds of that time, we can be sure that Caesar fought against mastiffs in 55 BC when he invaded Britain. Apparently, the dogs were impressive in battle, showing both great loyalty and strength.
