BRIEF HISTORY:

The Thai Ridgeback Dog is an old breed which can be seen in the archeological writings in Thailand which were written about 350 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.

GENERAL APPEARANCE: 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.
PROPORTIONS: Length of body : size (height at the withers) = 11 : 10
Depth of chest : size (height at the withers) = 1 : 2
BEHAVIOUR/TEMPERAMENT: Tough and active with excellent jumping ability. A loyal family dog.

Skull:

The skull is flat between the ears but slightly rounded when seen from the side.

Clearly defined, but moderate.
FACIAL REGION:
Nose: Black. In blue dogs, the nose is bluish.
Nasal bridge: Straight and long.
Muzzle: Wedge-shaped, slightly shorter than skull.
Lips: Tight with good pigmentation.
Mouth:  Black marking on the tongue is preferable.
Jaw: Upper and lower jaws are strong.
Teeth: White and strong with scissors bite.
Eyes: Medium size and almond shaped. The eye colour is dark brown. In blues, amber-coloured eyes are permitted.
Ears: Set on sides of the skull. Medium sized, triangular, inclining forward and firmly pricked. Not cropped.

LIMBS:
FOREQUARTERS:
Shoulder: Well laid back.

Hocks: Strong and well let down.
Rear Pastern: Straight and parallel when seen from the rear.
Feet: Oval
GAIT: 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.
SKIN:  Soft, fine and tight.
THROAT: No dewlap.
COAT:
HAIR: 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.

- 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).
FAULTS: - Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree.
- Any bite other than scissors bite.
- Unbalanced ridge.
ELIMINATING FAULTS: - Dogs without ridge.
- Long hair.
N.B. Male animals should have two apparently normal testicles fully descended into the scrotum.
