Mastiff
AKC & CKC Working Group
Origin & History
The Mastiff is one of the oldest dog breeds, with roots tracing back to ancient civilizations over 5,000 years ago. These massive dogs were used as war dogs by the Romans and as estate guardians in medieval England. The modern Mastiff was developed in England, where they were prized for their strength and used to guard castles and hunt large game.
Today, while still imposing protectors, most Mastiffs serve as gentle family companions, maintaining their calm demeanor and loyalty. Their massive size and noble bearing continue to command respect while their affectionate nature wins hearts.
As one of the heaviest dog breeds, the Mastiff remains a living link to ancient canine history while forming deep bonds with their human families.
