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 breed has fewer genetic health problems than many breeds, but cases can be found of hypothyroidism, entropion, ectropion, distichiasis, skin problems including allergies, autoimmune problems including demodex, Addison's disease, Cushing's disease, missing teeth, malocclusion (overbite, underbite, dry mouth), cardiac problems, seizures, epilepsy, progressive retinal atrophy (PRA), cataracts, and small ear canals with a tendency for infection. As with most large breeds, some will suffer with elbow or hip dysplasia.
