Foxton

The Boston Terrier is a compact, well-muscled dog that presents a square, balanced appearance reflecting its refined terrier heritage. Standing twelve to seventeen inches tall at the shoulder, the breed is divided into three weight classes: under fifteen pounds, fifteen to twenty pounds, and twenty to twenty-five pounds. The body is short-backed with a deep chest and well-sprung ribs, creating a sturdy frame that appears neither blocky nor chunky. The breed's hallmark tuxedo markings give it a distinguished, gentlemanly appearance that has earned it the nickname the American Gentleman. The topline is level with a slightly arched neck that carries the head gracefully, while the loins are short and muscular. The head is the breed's most distinctive feature, with a square, flat skull free from wrinkles and flat cheeks that create a clean, chiseled appearance. The brow is abrupt with a well-defined stop, and the expression is alert and kind, indicating high intelligence. The eyes are large, round, and dark, set wide apart and positioned square in the skull, giving the breed its characteristic appealing expression. The muzzle is short, square, and wide, proportionate to the skull without excessive wrinkling. The ears are small and stand erect, either naturally or cropped, positioned as near to the corners of the skull as possible. The jaw is broad and square with short, regular teeth meeting in an even bite or being slightly undershot. The coat is short, smooth, bright, and fine in texture, lying close to the body and requiring minimal grooming. Color and markings are strictly defined: brindle, seal, or black with white markings in a specific pattern. Required white markings include a muzzle band, blaze between the eyes, and white forechest. Desired markings include a white muzzle band, even white blaze between the eyes and over the head, white collar, white forechest, white on part or all of the forelegs, and white below the hocks on the rear legs. The tail is set low, short, fine, and tapering, carried horizontally and never above the back.

The Toy Fox Terrier is a diminutive yet athletic breed that combines the elegance of a toy dog with the athletic prowess of a true terrier. Standing eight and a half to eleven and a half inches tall at the shoulder and weighing between four and nine pounds, this breed presents a square, well-balanced appearance that belies its small stature. The body is compact with a level topline, well-developed chest, and moderate tuck-up, creating an outline that suggests agility and speed. Despite their tiny size, Toy Fox Terriers possess surprising muscle definition and athletic capability, making them one of the most agile toy breeds and skilled competitors in various dog sports. The head is elegant with a slightly rounded skull that is moderately wide and somewhat wedge-shaped when viewed from above. The muzzle is strong and rather fine, tapering gradually to a black nose on dogs with black head markings or a self-colored nose on chocolate dogs. The eyes are round, dark, and bright, set well apart and conveying an expression of intelligence and alertness characteristic of the terrier breeds. The ears are perhaps the breed's most striking feature: large, erect, and pointed, set high on the head in an inverted V-shape that gives the Toy Fox Terrier its distinctive, alert appearance. The ears should be held firmly erect in any dog over six months of age. The coat is short, smooth, satiny, and fine in texture, lying close to the body with a slight sheen that reflects the dog's good health. The coat is slightly longer at the ruff and may have sparse coverage on the belly. The breed comes in several color patterns, all featuring a predominantly white body with colored patches. Acceptable patterns include tri-color (white with black and tan patches), white with chocolate and tan, white with black, and white with tan. The head is predominantly colored, with the body being at least fifty percent white. The tail is set high, docked to approximately three-fifths of original length, and carried erect.
