Coat and looks how to spot one

short, smooth coat with a dorsal ridge

A sleek, short coat that lies close to the body. Along the spine runs a clearly outlined strip of hair growing against the rest of the coat, which should sit evenly on both sides of the backbone. Small whorls at the front of the ridge are allowed.13

Coloursredblackblueisabella (very light fawn)132

Personality what they are like

A tough, lively and quick-witted dog that forms a close bond with its own people. It tends to keep a polite distance from strangers, which makes it an attentive watchdog, and it has an independent streak that rewards patient, consistent handling.134

Daily activity how busy a day looks

An energetic breed that should get at least an hour of activity a day, split across walks and play such as fetch, running or swimming. Its jumping skill means secure, high fencing is sensible.43

Grooming and care the hands-on bits

Very easy coat care: a weekly brush, a little more often during seasonal shedding, plus routine nail, ear and tooth care.4

Home where they are happiest

Does best with an active household and a securely fenced garden. The thin, short coat is made for warm weather, so it appreciates protection from cold conditions.43

Food basics what goes in the bowl

A complete, good-quality dog food suited to its age, with treats kept to a small share of daily calories.4

Company who they like around

Very attached to its family and happiest living closely with them; early, gentle socialisation helps it meet new people calmly.43

The story where it all began

A long-established hunting and guard dog of eastern Thailand, mentioned in Thai writings from around the 17th century. It was used to hunt, escort carts and watch homes, and remote living conditions kept the breed largely unmixed. It remains uncommon outside Thailand.13

Fun facts for the dinner table

    It is one of only three purebred breeds with a ridge of backward-growing hair along the spine.3

  2. 2

    Breed fans describe eight ridge shapes, with names such as needle, feather, arrow, violin, bowling pin, leaf and saddle.2

  3. 3

    Genetic work suggests the ridge in Thai and African ridgebacks comes from the same ancient mutation.2

  4. 4
