BRIEF HISTORICAL SUMMARY

:
FCI
The Thai Ridgeback Dog is an old breed which can be seen in the archeological documents in Thailand which were written about 360 years ago. It was used mainly for hunting in the eastern part of Thailand. People also used it to escort their carts and as a watch dog. The reason why it has kept its own original type for so many years is due to poor transportation systems in the eastern part of Thailand; it had fewer chances to crossbreed with other breeds.
UKC
The origin of the Thai Ridgeback is unknown but the breed developed in eastern Thailand, where the breed was kept pure by isolation. Descriptions of the breed can be found in written references dating back to the 17th century. The breed’s name comes from a ridge of hair that runs along the dog’s back, a trait found in only three breeds of purebred dogs. The Thai Ridgeback was used for hunting, and as a guard dog. Today the breed is still very rare outside of Thailand. The Thai Ridgeback was recognized by the United Kennel Club on January 20, 1996.

GENERAL APPEARANCE

:
FCI
Medium-sized dog with short hair forming a ridge along the back. The body is slightly longer than its height at withers. Muscles are well developed, and its anatomical structure is suitable for activities.
UKC
The Thai Ridgeback is a medium-sized pariah-type dog, with a wedge-shaped head, prick ears, and a short, smooth coat. The length of body from point of buttocks to point of sternum is about 10 percent longer than the height measured at the withers. The depth of chest is equal to the length of the foreleg. The tail is carried vertically or curved like a sickle.

IMPORTANT PROPORTIONS

:
FCI

Length of body Height at the withers = 11 : 10
Depth of chest Height at the withers = 1 : 2

BEHAVIOUR / TEMPERAMENT

:
FCI
Tough and active with excellent jumping ability. A loyal family dog.
UKC
This breed is characterized by a ridge of hair growing in the opposite direction to the rest of the coat. This ridge starts at the withers and extends down the spine to the top of the pelvis bones. This breed is very active and agile, with excellent jumping and climbing abilities. They are devoted to family members but are inclined to be wary of strangers.

HEAD

:
UKC
The head is proportional to the size of the body. Viewed from the front, the Thai Ridgeback head forms a vertically elongated octagon. The octagonal shape is formed by a flat line between the ears; a line sloping downward and outward from the inside corner of the ear to the outside corner of the ear; a straight line downward from the outside corner of the ear to the point of the jawbone; a line slanting downward and inward from the point of the jawbone to the lower outside corner of the muzzle; a short, horizontal line across the bottom of the muzzle; and three corresponding lines around the other side of the face. Viewed from above and from the side, the head is wedge-shaped. The top lines of the skull and muzzle are roughly parallel to one another when viewed from the side, and joined by a well-defined, but not abrupt, stop. The ratio of muzzle length to skull length is 2:3. Supraorbital arches over the eyes are well defined but not pronounced. The forehead is wrinkled when the dog is attentive. Black marking on the tongue is preferable.

The ribs are moderately sprung out from the spine, forming a strong back. The back is level and well muscled with a broad, muscular, slightly arched loin. The chest is moderately wide and the brisket extends to the elbow. The forechest should extend in a shallow oval shape in front of the forelegs, but the sternum should not be excessively pointed.

LIMBS

:

FOREQUARTERS

Shoulder

:
FCI

FORELEGS

:
UKC
The muscles of the upper leg are firm and well developed. The forelegs are straight, with strong, moderately short, very slightly sloping pasterns, and moderate bone. The shoulder blade and the upper arm are roughly equal in length. The upper arm lies close to the ribs but is still very mobile, with the elbow moving close to the body.

Forearm

:
FCI

GAIT / MOVEMENT

:
FCI
Reachy stride with no pitching nor rolling of the body. Parallel tracking at normal speed. When viewed from the front, the forelegs move up and down in straight lines so that the shoulder, elbow and pastern joints are approximately in line with each other. When viewed from the rear, the stifle and hip joints are approximately in line. Movement in a straight line forward without throwing the feet in or out; thus enabling the stride to be long and drive powerful. The overall appearance of the moving dog is one of smooth flowing and well balanced rhythm.
UKC
Correct movement is essential in this breed. The Thai Ridgeback moves with strides of moderate length in a quick, agile trot. The forelegs and hind legs are carried straight forward, with neither elbows nor stifles turned in or out. While the dog is gaiting, the topline remains firm and appears level.
