Height: 5–8 inches
A graceful, alert, swift-moving compact little dog with saucy expression, and with terrier-like qualities of temperament
A well rounded "apple dome" skull, with or without molera. Expression – Saucy. Eyes - Full, round, but not protruding, balanced, set well apart-luminous dark or luminous ruby. Light eyes in blond or white-colored dogs permissible. Blue eyes or a difference in the color of the iris in the two eyes, or two different colors within one iris should be considered a serious fault. Ears – Large, erect type ears, held more upright when alert, but flaring to the sides at a 45 degree angle when in repose, giving breadth between the ears. Stop – Well defined. When viewed in profile, it forms a near 90 degree angle where muzzle joins skull. Muzzle – Moderately short, slightly pointed. Cheeks and jaws lean. Nose – Self-colored in blond types, or black. In moles, blues, and chocolates, they are self-colored. In blond types, pink noses permissible. Bite – Level or scissors. Overshot or undershot, or any distortion of the bite or jaw, should be penalized as a serious fault. A missing tooth or two is permissible. Disqualifications – Broken down or cropped ears.
Muscular, with hocks well apart, neither out nor in, well let down, firm and sturdy. Angulation – Should equal that of forequarters. The feet are as in front. Dewclaws may be removed.
In the Smooth Coats, the coat should be of soft texture, close and glossy. (Heavier coats with undercoats permissible.) Coat placed well over body with ruff on neck preferred, and more scanty on head and ears. Hair on tail preferred furry. In Long Coats, the coat should be of a soft texture, either flat or slightly wavy, with undercoat preferred. Ears – Fringed.
Any color - Solid, marked or splashed.
Full and long (as a plume). Feathering on feet and legs, pants on hind legs and large ruff on the neck desired and preferred. (The Chihuahua should be groomed only to create a neat appearance.) Disqualification - In Long Coats, too thin coat that resembles bareness.
The Chihuahua should move swiftly with a firm, sturdy action, with good reach in front equal to the drive from the rear. From the rear, the hocks remain parallel to each other, and the foot fall of the rear legs follows directly behind that of the forelegs. The legs, both front and rear, will tend to converge slightly toward a central line of gravity as speed increases. The side view shows good, strong drive in the rear and plenty of reach in the front, with head carried high. The topline should remain firm and the backline level as the dog moves.
Charming, Graceful, Sassy
Any dog over 6 pounds in weight. Broken down or cropped ears. Docked tail, bobtail. In Long Coats, too thin coat that resembles bareness.
