Alangu Mastiff
ah-LAHN-goo MAS-tif
India· Tamil Nadu, South India
The Alangu Mastiff is an archaic molosser-type dog native to parts of southern India, historically associated with the Thanjavur and Tiruchirappalli districts of Tamil Nadu. Written records are exceptionally scarce, and canine historians debate whether the original strain survives in its pure form or whether it has largely been assimilated into broader regional mastiff populations, such as the Bully Kutta. Where referenced in historical accounts, it is described as a powerful, tall, and heavy-boned guardian.

The long read
About the breed
Historically kept by regional royalty and landed estates, the Alangu was traditionally deployed for big-game hunting—including wild boar and stag—as well as territory defence and personal protection. The breed was valued for its great endurance in high temperatures, physical strength, and resolute guarding instinct, demanding firm management from experienced handlers.
Today, the Alangu Mastiff is considered exceedingly rare, and some authorities suggest it may be critically endangered or functionally extinct as a distinct, registered breed. Many contemporary dogs described as Alangu Mastiffs represent working landraces or crossbreeds. Because documented breed registries are lacking, physiological and behavioural summaries must be interpreted with caution based on historical documentation.

The points of the breed
Hover or tap a numbered point to read what the standard asks for.

Point 1
Skull
The Alangu Mastiff's skull is judged on balance rather than size — proportionate to the body, with a clean cheek and a stop typical of the breed. Coarseness or an over-refined head are both faulted.

Timeline
History & development
c. 16th–18th Century
Feudal Guardians
Maintained by regional chieftains and aristocrats in southern India for hunting wild boar and guarding fortified estates against intruders.
Late 19th Century
Colonial Documentation
British colonial observers recorded large, powerful mastiff-like hounds in the Madras Presidency, noting their formidable temperament and working utility.
Late 20th Century to Present
Decline and Rarity
With the decline of feudal estates and traditional hunting, purebred numbers dwindled sharply, leading to extensive interbreeding with related northern Indian and Pakistani mastiffs.

Health
What to screen for
Green means little to worry about, amber means ask the breeder for test results, red means manage it actively.
Gastric Dilatation-Volvulus (Bloat)
Screen for it
Deep-chested mastiff anatomy places these dogs at elevated risk of life-threatening stomach twisting.
Joint and Musculoskeletal Issues
Screen for it
Substantial body mass can predispose rapid-growing puppies and adults to hip and elbow dysplasia.
Heat Regulation
Watch closely
Though adapted to tropical climates, extreme exertion in direct sun can overwhelm large, heavy molossers.
