Taco Terrier

The Chihuahua holds the distinction of being the smallest recognized dog breed in the world, typically standing between five and eight inches at the shoulder and weighing no more than six pounds according to American Kennel Club breed standards. Despite their diminutive size, Chihuahuas possess a compact, well-balanced body that is slightly longer than it is tall, carrying themselves with a confident, terrier-like attitude that belies their tiny stature. The breed displays remarkable variation in appearance, coming in two distinct coat varieties and two head shapes, allowing for considerable diversity within breed standards while maintaining the breed's characteristic sassiness. The smooth coat variety features short, close-lying hair that appears glossy and soft to the touch, while the long coat variety displays longer, flat or slightly wavy hair with distinctive feathering on the ears, chest, legs, and a fully plumed tail. Both coat types come in virtually any color or combination of colors, including solid, marked, and splashed patterns, with fawn, black, white, chocolate, cream, and various combinations being common throughout the breed. The breed standard permits almost all colors except merle in some registries due to health concerns associated with that pattern. A distinctive feature of the breed is the molera, a soft spot on the skull similar to a human infant's fontanel, which may or may not close completely as the dog matures and is considered a breed characteristic. Two distinct head shapes are recognized in the breed, each with devoted followers among Chihuahua enthusiasts. The apple head, which is preferred in show rings, features a well-rounded skull dome with a prominent forehead and a well-defined stop where the muzzle meets the skull. The deer head variety displays a longer muzzle, flatter skull, and more angular features reminiscent of a young deer. Both types share the breed's characteristically large, erect ears that stand at approximately a forty-five-degree angle from the head and prominent, round, expressive eyes that are typically dark but may be lighter in dogs with lighter coat colors such as cream or white.

The Toy Fox Terrier is a small, elegantly proportioned breed that combines the athleticism and tenacity of a terrier with the diminutive size of a toy dog. Standing between 8.5 and 11.5 inches at the shoulder and typically weighing between 3.5 and 7 pounds, this breed displays a square, well-balanced build with a level topline and a body that appears athletic and capable despite its small stature. The breed's refined appearance reflects its dual heritage as both a working ratter descended from larger Fox Terriers and a treasured companion bred for its compact size and engaging personality. The coat of the Toy Fox Terrier is distinctive in its short, satiny texture that lies smooth and close to the body, feeling fine and sleek to the touch with a glossy appearance that reflects good health. A slight increase in coat length appears at the ruff around the neck and shoulders, adding to the breed's elegant profile. The predominant body color is white, comprising more than fifty percent of the coat, with a predominantly solid-colored head that may display several recognized patterns including tricolor featuring black and tan markings, white and tan, white and black, or white with chocolate and tan combinations. A white blaze on the face is acceptable and often present according to breed standards. The head is elegant and finely chiseled with a slightly domed skull that tapers toward the muzzle without being snippy or weak. Large, erect, V-shaped ears set high on the head are a distinctive and charming feature of the breed, pointing upward and slightly outward, giving the dog an alert, intelligent appearance. Round, dark eyes express an alert and curious demeanor that reflects the breed's keen awareness of its surroundings and quick mental processing. The muzzle is strong and slightly tapering, with a black nose in most color varieties though chocolate may appear in dogs with chocolate markings. The tail is set high and carried erect, traditionally docked in the United States though natural tails are acceptable and required in many other countries.
