Molosser Dog Breeds

The name “Molosser” derives from Molossia, a subregion of ancient Epirus, in North-West Ancient Greece. Molossers are sometimes called “mastiffs”. The proper noun “Mastiff”, however, is used to refer to the English Mastiff, a breed that originated in England over two thousand years ago. Other terms include “Mastín” (Spanish), “dogge” (Germanic), and “dogue” or “dogo” (Romance languages).

Breeds such as the Bullmastiff, Dogue de Bordeaux, Fila Brasileiro, Mastin Del Pirineo, Spanish Mastiff, Neapolitan Mastiff, Tibetan Mastiff, and many others fall into the larger category of “Molossers”, but are not “Mastiffs”. Each is a separate and distinct breed. The Boxer breed is also included, as it is a creation from other Molossers including the Original English Bulldog.

Molossers typically have heavy bones, pendant ears, a relatively short and well-muscled neck, and a short muzzle. Although some Molossers are used for search and rescue, such as the Newfoundland and the Saint Bernard, most are used as guard dogs, due to their deep voices and natural guarding instincts, or livestock guardian dogs for protection against large predators as well as poachers. Some breeds like the Greater Swiss Mountain Dog have also been used as cart dogs.

The first known record of a molosser-like dog was in 1121 BC, when a Tibetan mastiff trained for hunting was given to a Chinese emperor. The mastiffs would later be imported to Mongolia, Mesopotamia and Central Asia where they would mix with local dogs, resulting in a loss of long hair and colour uniformity. The main features, such as height and a massive head with a big short muzzle were kept. The dogs were considered valuable in Babylon, and are mentioned in cuneiform in the 4th century BC. A large mastiff-like dog is shown on the ancient terracotta by Byrs Nimruda. The dog is rather tall: 90 cm at the withers, has a stocky head and powerful hind quarters. The dogs were used for hunting in ancient Assyria. Archeological digs of the Ashurbanipal palace (7th century BC) revealed pictures of dogs felling wild horses and donkeys. Assyrian mastiffs were also used for military purposes and for protection.

The ancient mastiffs would later be imported from Assyria and Babylon to Egypt and Asia Minor. Xerxes I of Persia led predatory wars to enlarge the borders of his empire, taking with him large war dogs in his Army. After his army’s defeat by the Spartans, the mastiffs were taken to Greece as trophies of war. The mastiffs would be bred in Molossia and from there, spread all over the Mediterranean under the name of “epirian” dogs or molosses.

The Alans kept mastiff-like dogs taken from Eastern Europe which acted as retrievers, watchdogs and fighting dogs. The mastiffs were used in unison with sighthounds to hunt Wisent, aurochs and bears. Groups of Alanian tribes came to Europe during the Migration Period, fighting on the territory of modern France, Spain, Portugal and Northern Africa, taking with them their dogs. The Alanian mastiffs then spread to the British Isles.

The Bulldog breeds split from the Molossers in England and spread to the New World with colonization as well as Western Europe and, though smaller, are considered by some to still be Molosser breeds.
