FCI standard 368
Transmontano Mastiff.
Flock guardian against wolf. FCI 368 utilization: livestock guarding dog for sheep and goat flocks. History: evolution tied to the Peninsular transhumance routes; a companion of the shepherd with specific duties guarding against wolf attacks, wolves being long abundant in Trás-os-Montes; settled in the Portuguese highlands where steep, hard-to-reach pastures shaped the breed. Temperament: docile but reserved, cautious without being aggressive, calm; an exceptional guard protecting flocks against wolf attacks. CPC: livestock guarding dog for sheep and goat flocks. Grupo Lobo: still widely used to protect livestock, mainly sheep; a very recent breed, first registrations in 2004 and standard definitively recognised in 2012; the largest Portuguese breed; Grupo Lobo's Programa Cao de Gado places puppies of four Portuguese breeds, the Transmontano among them, with livestock owners to cut wolf losses. Wikipedia (English): more than 95% of the dogs guard sheep flocks; defends against wild boar, foxes, wolves and feral dogs; an excellent night guardian; needs large space and is ill-suited to chains or apartments; Portugal keeps a registry and, with Grupo Lobo, supports placing the dogs to protect flocks from wolves.
Breed sets the odds. The parents set the dog. Every number here shows its source, its spread and how sure we are. Nothing on this page is a prediction about one dog.
The body
What the breed is built like. Registry standards give an ideal, not a range.
Height at the shoulder
Four sources print 68-78 cm; Portuguese Wikipedia prints 66-76 cm, so low widens to 26.0 in (66 cm / 2.54). No ideal printed, center blank.
Weight
Four sources print 50-60 kg; Portuguese Wikipedia prints 45-60 kg, so low widens to 99.2 lb (45 kg x 2.20462). No ideal printed.
Coat
Heat tolerance
Derived from the coat description in the standard (confidence derived). 3 = medium double coat.
The work
What it was built to do in the field, and what a test or trial asks of it.
Role
Role is stated by FCI, CPC, Grupo Lobo and Wikipedia. The programme-wide Grupo Lobo result (74 percent of 90 owners reported reduced wolf losses) is not breed-specific and is not used as a figure.
Search pattern
FCI and CPC (same text, separate publishers).

Every value carries a label. Measured means peer-reviewed data on many dogs. Studied means peer-reviewed, smaller or indirect. Breed club means a club or registry states it.
