The world’s smallest dog, the Chihuahua is the breed of dog considered truly indigenous to the Western Hemisphere. The breed’s name indicates its ancestors came from the State of Chihuahua in Mexico. However, the breed’s origins more properly belong to the whole of the country. It is thought that the Chihuahua is derived from an earlier breed known as Techichi, popular during the Toltec period, around the 7th century A.D. It is said that the Long Coat Chihuahua was developed entirely in the United States by crossing the Short Coat Chihuahua to the Papillon and the Pomeranian. The Chihuahua has evolved primarily as a human companion.

Head Skull: Well-rounded apple-dome skull, with or without molera. Cheeks and jaws lean. Muzzle moderately short, slightly pointed. Nose selfcoloured in blonde types, or black.

Eyes full, but not protruding, balanced, set well apart – dark, ruby or luminous. (Light eyes in blond types permissible.) Ears large, held erect when alert, but flaring at the sides at about an angle of 45 degrees when in repose. This gives breadth between the ears.
Neck: Slightly arched, gracefully sloping into lean shoulders, may be smooth in the very short types, or with ruff about neck preferred.
Forequarters: Shoulders lean, sloping into a slightly broadening support, well up, giving balance and soundness. Upper arm set on to give chestiness and strength of forequarters, yet not of the bulldog chest. Lower arm – forelegs straight, set well under, giving free play at the elbow. Pasterns fine. Feet – a dainty small foot with toes well split up, but not spread, pads cushioned, with nails moderately long. (Neither the hare nor the catfoot.)

Hindquarters: Hipbone well covered. Upper thigh muscular, in balance with front assembly. Lower thigh muscular, in balance with front assembly. Hocks well apart, turning neither in nor out, well let down, with firm sturdy action. Stifle bend – well bent and strong. Feet – a dainty small foot with toes well split up, but not spread, pads cushioned, with nails moderately long. (Neither the hare nor the cat-foot.)
Tail: Moderately long, carried sickle either up or out, or in a loop over the back with tip just touching the back. (Never tucked under.) Hair on tail in harmony with the coat of the body, preferred furry.
Gait: A graceful, swift and flowing straight forward movement with good reach and strong drive.
Serious Faults: Undershot, overshot, weighing more than 6 lb. (2.7 kg); bobtail.
Disqualifications: Cropped tail, broken down or cropped ears. Merle colour.
