Some breeders differentiate between two 'types' of Tibetan Mastiff, the Do-khyi (-gs is not pronounced in Lhasa Tibetan) and the Tsang-khyi. The Tsang-khyi (which, to a Tibetan, means only 'dog from Tsang') is also referred to as the 'monastery' type, described as generally taller, heavier, and more heavily boned, with more facial wrinkling and haw than the Do-khyi or 'nomad' type. Both types are often produced in the same litter with the larger, heavier pups being placed in more stationary jobs versus more active jobs for the Tibetan Mastiffs that are better structured and well-muscled. Males can reach heights up to 83 cm (33 in). The original Tibetan Mastiff breed from its native range usually weighed 55–90 kg (121–198 lb).
