Coat and looks how to spot one

medium to long double coat

A hard, straight outer coat that stands away from the body over a thick woolly undercoat in the cold months. Males carry noticeably more coat, forming a lion-like mane over the neck and shoulders. Quality matters more than sheer volume.12

Coloursblackbluegold (fawn to deep red)sableany of these with tan markings12

Personality what they are like

A self-assured, independent guardian that is gentle and devoted with its own family but reserved and watchful with outsiders. It tends to be settled in the house and most alert in the evening and at night, true to its sentry heritage.142

Daily activity how busy a day looks

Moderate: up to about an hour of exercise a day is enough for most adults.3

Grooming and care the hands-on bits

Brushing more than once a week, with extra work during the yearly heavy moult of the undercoat in late winter or spring.32

Home where they are happiest

Best in a large home with a spacious, securely fenced garden, in town or country; it is not an apartment dog and suits experienced owners.32

Company who they like around

Strongly bonded to its household and territory; thoughtful socialisation from puppyhood helps it accept visitors calmly.12

The story where it all began

An ancient working dog of Himalayan herders and a traditional guardian of Tibetan monasteries. Reports of huge Tibetan dogs reached Europe over centuries; Queen Victoria received one in 1847 and dogs were shown in Britain in the early 1900s. Worldwide interest in the breed grew strongly from the 1980s.12
