what is the size of a tibetan mastiff
Tibetan Mastiff 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). The enormous dogs being produced in some Western and Chinese kennels, which sometimes weigh in excess of 115 kg (254 lb) would have cost too much to keep fed to have been useful to nomads; and their questionable structure would have made them less useful as livestock or property guardians.
