Thai Ridgeback
dog breed
The Thai Ridgeback (Thai: ไทยหลังอาน, RTGS: Thai lang-an) is a dog breed from Thailand.
Appearance
Eight distinctive ridge patterns have been identified: needle, feather, arrow, lute, violin, bowling pin, leaf, and saddleback. All patterns are acceptable, but must be clearly defined and symmetrical. The broader the ridge, the more highly it is prized.
Genetics
Ridge
The ridgeback is under a control of two groups of epistatic genes. The first determines the existence of the ridge. The other determines the size of the ridge, from none to very large (down to the side) the latter, the more the genes in the dog, the broader is the ridge. The ridge will appear only if there is at least one dominant allele in both groups.
History
The Rhodesian Ridgeback is partly descended from the southern African indigenous Hottentot Khoi dog, a known ridge-bearing dog. The gene that causes the ridge has been inherited from a common ancestor: "The geographical origin of the ridge present in Ridgeback dogs is still a mystery, thus solid proof has now been provided that the ridge mutation in Ridgeback dogs is identical by descent and the likelihood of parallel mutations occurring in Asia and Africa (Epstein, 1937) can therefore be rejected."
Grooming
The Thai Ridgeback has a short coat that is easily cared for with a weekly brushing.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 21, 2026. The linked authority identifier is Q39172. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1937.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
