Ratshire Terrier

The Yorkshire Terrier is a diminutive yet perfectly proportioned toy breed that carries itself with an air of self-importance and confidence far exceeding its small size. The breed standard specifies a maximum weight of seven pounds, with most quality specimens weighing between four and seven pounds, though there is no official height standard in most registries. These dogs typically stand approximately six to nine inches at the shoulder. Despite their petite stature, Yorkshire Terriers display a compact, well-balanced body structure with a level topline and moderate bone that provides adequate substance without appearing coarse or delicate. The breed's most celebrated feature is its exquisite coat, which is long, perfectly straight, silky in texture, and glossy in appearance. Unlike many breeds, the Yorkshire Terrier's coat more closely resembles human hair than typical dog fur, growing continuously and requiring regular trimming if not kept in show condition. The coat parts naturally from the skull to the base of the tail and hangs evenly on each side of the body. The distinctive coloring follows a precise pattern: a rich, golden tan on the head, chest, and legs, combined with a dark steel blue covering the body from the back of the head to the root of the tail. Puppies are born black and tan, gradually developing their adult coloring over the first two to three years. The Yorkshire Terrier's head is small and rather flat on top, with a medium-length muzzle that is not overly prominent. The dark, sparkling eyes convey a sharp, intelligent expression characteristic of the breed's keen terrier temperament. Small V-shaped ears are carried erect, set moderately high on the head, adding to the alert appearance. The nose is black, and the teeth meet in a scissors or level bite. The tail is customarily docked to medium length in countries where this practice remains legal, carried slightly higher than the level of the back. The overall impression is of a spirited, determined little dog with an elegant, refined appearance.

The American Rat Terrier is a compact, well-muscled small to medium-sized dog that presents an appearance of elegance combined with athletic capability. This breed comes in two distinct size varieties recognized by major kennel clubs: the Miniature, standing between 10 and 13 inches at the shoulder, and the Standard, measuring over 13 inches up to 18 inches in height. Weight varies proportionally with height, though the breed standard emphasizes moderate bone structure and a well-balanced physique rather than specific weight requirements. The body is slightly longer than tall, with a level back, well-sprung ribs, and a moderately wide chest that extends to the elbow. The breed's coat is short, smooth, dense, and characteristically shiny, requiring minimal grooming to maintain its healthy appearance. American Rat Terriers display a distinctive pied coloring pattern, featuring comparatively large patches of one or more colors combined with white. Acceptable colors include black, chocolate, red, apricot, blue, fawn, tan, and lemon, often appearing with tan points. The breed standard specifies that white should comprise between 10 and 90 percent of the coat, and solid-colored dogs without white markings are not permitted. The intense, dark shades with clearly defined color delineation are preferred in show specimens. The head resembles a smooth, blunt wedge when viewed from the front or in profile, widening gradually toward the base of the ears. The expression is intelligent, alert, and full of interest, achieved through obliquely set oval eyes that are positioned wide apart. Ears are set on the outside edge of the skull and may be carried erect, semi-erect, or tipped. The muzzle is strong and slightly shorter than the skull, tapering slightly toward the nose. The tail may be naturally bobbed, docked, or left full length, carried from slightly below horizontal to nearly erect depending on the dog's mood and attention level.
