...that an Old English Mastiff holds the record for being the heaviest dog? In 1989, "Zorba", a Mastiff in London, weighed 155.58 kg (343 lbs).

...that Mastiff's were recruited as dogs of war during the Roman Empire as well as the Middle Ages? The Romans trained the courageous Mastiffs to fearlessly attack their enemies. During the Middle Ages, the Mastiff was sent into battle against mounted knights. Not entirely defenseless, the Mastiff was geared up with his own coat of armor. With a deadly iron spike set on his head and a cauldron of hot sulfur and resin placed on his back, the Mastiff was transformed into a fearsome warrior.

...Most domestic dogs are capable of reaching speeds of 32 kms per hour when running flat out but the members of the greyhound family may reach speeds up to 70 kms per hour.
