Do you know 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)! Mastiffs were war dogs during the Roman Empire and the Middle Ages. They fearlessly attacked their enemies while geared up in coats of armor. With a deadly iron spike set on their heads, Mastiffs were transformed into fearsome warriors! Imagine these huge dogs on your side in war. What frightening friends they would be!
