General Appearance
The Shiba is the smallest of the Japanese native breeds of dog and was originally developed for hunting by sight and scent in the dense undergrowth of Japan's mountainous areas. Alert and agile with keen senses, he is also an excellent watchdog and companion. His frame is compact with well-developed muscles. Males and females are distinctly different in appearance: males are masculine without coarseness, females are feminine without weakness of structure.

Males 14½ inches to 16½ inches at withers. Females 13½ inches to 15½ inches. The preferred size is the middle of the range for each sex. Average weight at preferred size is approximately 23 pounds for males, 17 pounds for females. Males have a height to length ration of 10 to 11, females slightly longer. Bone is moderate. Disqualification--Males over 16½ inches in dogs and under 14½ inches. Females over 15½ inches and under 13½ inches.

Forechest is well developed. Chest depth measured from the withers to the lowest point of the sternum is one-half or slightly less than the total height from withers to ground. Ribs are moderately sprung. Abdomen is firm and well tucked-up. Back is firm. Loins are strong. Tail is thick and powerful and is carried over the back in a sickle or curled position. A loose single curl or sickle tail pointing vigorously toward the neck and nearly parallel to the back is preferred. A double curl or sickle tail pointing upward is acceptable. In length the tail reaches nearly to the hock joint when extended. Tail is set high.

Forequarters
Shoulder blade and upper arm are moderately anuglated and approximately equal in length. Elbows are set close to the body and turn neither in nor out. Forelegs and feet are moderately spaced, straight, and parallel. Pasterns are slightly inclined. Removal of front dewclaws is optional.

Coat
Double coated with the outer coat being stiff and straight and the undercoat soft and thick. Fur is short and even on face, ears, and legs. Guard hairs stand off the body are about 1½ to 2 inches in length at the withers. Tail hair is slightly longer and stands open in a brush. It is preferred that the Shiba be presented in a natural state. Trimming of the coat must be severely penalized. Serious Fault--Long or woolly coat.

Color
Coat color is as specified herein, with the three allowed colors given equal consideration. All colors are clear and intense. The undercoat is cream, buff or gray.

Urajiro (cream to white ventral color) is required in the following areas on all coat colors: on the sides of the muzzle, on the cheeks, inside the ears, on the underjaw and upper throat inside of legs, on the abdomen, around the vent and the ventral side of the tail. On reds: commonly on the throat, forechest, and chest. On blacks and sesames: commonly as a triangular mark on both sides of the forechest. White spots above the eyes permitted on all colors but not required.

Bright orange-red with urajiro lending a foxlike appearance to dogs of this color. Clear red preferred but a very slight dash of black tipping is permitted on the back and tail.

Black with tan points and urajiro. Black hairs have a brownish cast, not blue. The undercoat is buff or gray. The borderline between black and tan areas is clearly defined. Tan points are located as follows: two oval spots over the eyes: on the sides of the muzzle between the black bridge of the muzzle and the white cheeks; on the outside of the forelegs from the carpus, or a little above, downward to the toes; on the outside of the hind legs down the front of the stifle broadening from hock joint to toes, but not completely eliminating black from rear of pasterns. Black penciling on toes permitted. Tan hairs may also be found on the inside of the ear and on the underside of the tail.

Sesame (black-tipped hairs on a rich red background) with urajiro. Tipping is light and even on the body and head with no concentration of black in any area. Sesame areas appear at least one-half red. Sesame may end in a widow's peak on the forehead, leaving the bridge and sides of the muzzle red. Eye spots and lower legs are also red.

Clearly delineated white markings are permitted but not required on the tip of the tail and in the form of socks on the forelegs to the elbow joint, hind legs to the knee joint. A patch of blaze is permitted on the throat, forechest, or chest in addition to urajiro.

Serious fault--Cream, white pinto, or any other color or marking not specified is a very serious fault and must be penalized.

Gait
Movement is nimble, light, and elastic. At the trot, the legs angle in towards a center line while the topline remains level and firm. forward reach and rear extension are moderate and efficient. In the show ring, the Shiba is gaited on a loose lead at a brisk trot.

Temperament
A spirited boldness, a good nature, and an unaffected forthrightness, which together yield dignity and natural beauty. The Shiba has an independent nature and can be reserved toward strangers but is loyal and affectionate to those who earn his respect. At times aggressive toward other dogs, the Shiba is always under the control of his handler. Any aggression toward handler or judge or any overt shyness must be severely penalized.

Summary
The foregoing is a description of the ideal Shiba. Any deviation from the above standard is to be considered a fault and must be penalized. The severity of the fault is equal to the extent of the deviation. A harmonious balance of form, color, movement, and temperament is more critical than any one feature.
