An ancient heavyweight breed depicted in reliefs from before Christ. Calm, steady and deeply affectionate toward its family.
The Mastiff is a very old English breed descending from the Tibetan Mastiff, depicted hunting lions and wild horses in Babylonian reliefs from around 700 BC and brought to Rome after Julius Caesar's expedition to England. Famous for bear-baiting from the era of Edward I, it declined after the sport was banned in 1642 and was revived through dog shows, reaching its current standard about a century ago. A calm, deeply affectionate giant with guarding ability, it requires careful management of growth, space and health.
