Overview
The Thai Ridgeback is an ancient Thai breed distinguished by the ridge of hair growing in the opposite direction along its back. Muscular and athletic, it was bred to hunt, guard, and accompany travelers in eastern Thailand.
Loyal, independent, and protective, the Thai Ridgeback bonds closely with its family while remaining aloof and watchful with strangers. It is an intelligent, strong-willed dog with a prey drive, best suited to experienced owners.
History
Developed in eastern Thailand and long isolated, the Thai Ridgeback served as a hunter, guardian, and cart escort. Its geographic isolation preserved an ancient, hardy breed that remains relatively rare outside its homeland.

Temperament
The Thai Ridgeback is devoted, alert, and self-reliant, attached to family and wary of strangers. It is intelligent and strong-willed with a prey drive, needing early socialization, secure containment, and confident, consistent handling.
Health to watch
A ridge-related skin condition can occur; affected areas may need surgical correction, so screening helps.
Joint malformation occurs in active breeds; screening and lean weight help protect the hips over time.
As a landrace breed, the Thai Ridgeback is robust overall with relatively few inherited disorders.
