American Kennel Club (AKC)
The American Kennel Club standard for the Japanese Spaniel emphasizes the breed's aristocratic bearing and toy dog characteristics. General Appearance calls for a lively, high-bred toy dog with a distinctive Oriental expression, characterized by large eyes, pushed-in face, and feathery tail carried over the back. Size specifications require dogs to be small, compact, and square in outline, typically weighing between 4 and 15 pounds with most desirable weight being 7 to 9 pounds.
Head and Expression requirements specify a large skull that is broad and rounded, with a very short and broad muzzle. Eyes must be large, round, dark, and set wide apart with a soft, loving expression. The stop should be deep and well-defined. Ears are small, V-shaped, and set high and wide apart, carried slightly forward and feathered with long silky hair. The bite may be slightly undershot, even, or scissors, though a slightly undershot bite is preferred.
Body structure demands a square outline with height equaling length. The neck should be short and moderately thick, blending well into the shoulders. The chest is broad and deep, with well-sprung ribs. The back is short and square, and the loin is short with moderate tuck-up. Forelegs should be straight with fine bone, while hindquarters show moderate angulation with well-let-down hocks.
Coat specifications require a profuse, silky, soft, and straight single coat that is free from curl or wave. The coat should be shorter on the face and front of forelegs and hind legs below the hocks, with feathering on ears, neck, chest, back of forelegs, and thighs. The tail must be profusely coated and carried over the body. Color should be white with patches of either black or red, including all shades of sable, brindle, lemon, or orange. The more evenly marked the better, and patches should be evenly distributed on the head.
Fédération Cynologique Internationale (FCI)
The FCI standard, developed in cooperation with Japan as the country of origin, provides detailed specifications for the Japanese Spaniel under Group 9, Section 8 (Japanese Chin and Pekingese). General Appearance emphasizes a small, elegant, and well-balanced dog of dainty appearance with a distinctive Oriental expression. The breed should convey an impression of intelligence and alert dignity combined with a charming and aristocratic bearing.
Important proportions state that the body should be slightly longer than tall, with the ideal height being 25 cm with tolerance of 2 cm above or below for both sexes. Weight should be between 2 and 5 kg, with dogs under 2 kg being less desirable. The head length should be in proportion to the body size, with the skull width being greater than its length.
Behavior and Temperament descriptions emphasize a lively, happy, and charming nature with good-natured and affectionate qualities. The breed should be alert and intelligent, showing particular devotion to its master while remaining friendly toward strangers. Movement should be elegant and dignified, with a slightly rolling gait that is characteristic of the breed.
Detailed head specifications require a relatively large head in proportion to body size, with a broad and rounded skull. The stop must be well-pronounced and situated between the eyes. Eyes should be large, round, dark, and lustrous, set wide apart and looking straight ahead. The muzzle is very short and broad with a slightly upturned nose. Ears are small, triangular, and set wide apart and high on the head.
Coat and color requirements specify a long, silky, and straight coat that should not be curly or wavy. The coat is shorter on the face and front of legs but forms profuse feathering on the ears, neck, chest, back of forelegs, and thighs. Colors include white with patches of black or various shades of red, with symmetrical head markings being highly desirable.
United Kennel Club (UKC)
The United Kennel Club recognizes the Japanese Spaniel in the Companion Dog Group, emphasizing the breed's role as a devoted companion rather than a working dog. The UKC standard stresses the importance of soundness and correct temperament alongside the breed's distinctive physical characteristics. General appearance should convey elegance, refinement, and aristocratic bearing in a small, compact package.
Size requirements are flexible within reason, focusing more on overall balance and proportion than strict weight limits. Dogs should appear square when viewed from the side, with equal height and length measurements. The standard allows for some variation in size while maintaining the toy breed characteristics that define the breed's appeal and function.
Temperament specifications emphasize the breed's suitability as a companion dog, requiring a happy, alert, and intelligent nature. The breed should be naturally friendly and outgoing while maintaining dignity and poise. Shyness or aggressive behavior is considered undesirable and counter to the breed's fundamental character as developed over centuries of selective breeding.
Movement requirements call for a light, elegant gait that appears effortless and flowing. The characteristic slightly rolling motion should not interfere with forward progress or overall balance. The breed should move with confidence and purpose despite their small size, demonstrating the underlying soundness necessary for a healthy, long-lived companion.
