About
What is a Thai Ridgeback Dog?
An ancient, medium-sized hound known for the distinctive ridge of hair running along its back, with a muscular, athletic build and an independent, protective nature
Thai Ridgeback Dog history and origins
An ancient, primitive breed native to eastern Thailand, developed for hunting small game, vermin control, and serving as a guard dog. Its isolation in the region preserved its unique characteristics, including the dorsal ridge, for centuries. One of only three breeds with hair ridge.
Thai Ridgeback Dog appearance and size

Pros & cons
Pros & cons for the Thai Ridgeback Dog
What you get with the Thai Ridgeback Dog
- Purpose stated in the standard: “Hunting and companion dog”
- The standard describes the breed as: “Tough and active with excellent jumping ability. A loyal family dog”
- Low grooming needs, fitting for a busy owner — the coat is “Short and smooth. The ridge on the top region is formed by the hair growing in the…”
What you are taking on
- One serious inherited condition is documented, in skin & coat. The health guide tab has the test to ask a breeder for.
Drawn from sources rather than written as an opinion — cited health research, the registry’s own standard, and peer-reviewed longevity. FCI breed standard; Nature Genetics — Salmon Hillbertz et al. 2007, duplication of FGF3, FGF4, FGF19 and ORAOV1 causes hair ridge and predisposition to dermoid sinus in Ridgeback dogs. One breeder’s animals can differ from any of it, and an empty column means we hold nothing for that side rather than that there is nothing to say.
Characteristics
FCI standard · Thai Ridgeback Dog
Coat and colour
As the FCI standard sets it out. Every line below is the standard’s own wording, tagged preferred.
Coat
Short and smooth.
The ridge on the top region is formed by the hair growing in the opposite direction to the rest of the coat.
It should be clearly defined from other parts of the back.
There are various shapes and lengths of ridge, but must be symmetrical on either side of the backbone and within the width of the back.
Crowns or whirls at the head of the ridge are acceptable
Colour
- Preferred
- Permissible
- Undesirable
- Disqualifying
Preferred, permissible, undesirable and disqualifying are FCI’s own words about the breed. They describe what the standard asks for — not an assessment of any individual dog, and not ours.
Shortened from FCI standard n°338 — each label is the standard’s own wording with the verdict lifted into the tag beside it. Read the full clause at source.
What the breed standard says
- Size
- “Ideal height at the withers: Dogs 22-24 inches (56-61 cm) Bitches 20-22 inches (51-56 cm). There is a tolerance of plus or minus one inch (2.5 cm)”
- FCI states a tolerance around the figure.
Quoted from FCI standard n°338. It describes the breed the registry recognises, not any individual animal.
What the standard penalises
What a judge marks the Thai Ridgeback Dog down for, and what puts one out of the ring, in the registry’s own words. This describes the breed standard — it is not a checklist for the animal in front of you, and a pet with a disqualifying fault is an unshowable dog rather than an unhealthy one.
Disqualifying faults
Puts an animal out of the ring altogether.
- Dogs without ridge
- Long hair

Health & screening guide for the Thai Ridgeback Dog
Known hereditary risks for the Thai Ridgeback Dog breed, and the specific documentation to request from any breeder before paying a deposit. A responsible breeder will have these readily available; deflection is a red flag.

Health checklist (PDF)Skin & coat
Dermoid sinus
SeriousInherent to the breed
A tubular skin defect running along the dorsal midline towards the spine, present from birth, caused by the same FGF3/FGF4/FGF19/ORAOV1 gene duplication that produces the breed's ridge. It can trap debris, become repeatedly infected, and usually needs surgical removal; dogs with two copies of the duplication are at substantially higher risk than dogs with one.
What to ask for
A DNA 'ridge zygosity' test on both parents, showing whether each carries one or two copies of the duplication (offered for this breed specifically by GenoCan and other laboratories). This predicts relative risk, not presence — it does not replace a physical check of the puppy's back at birth and over the following weeks.
