Rat-Cha

The Chihuahua holds the distinction of being the smallest recognized dog breed in the world, with the American Kennel Club standard requiring dogs to weigh no more than six pounds. Standing only 5 to 8 inches tall at the shoulder, these tiny dogs possess a compact, slightly off-square body that is marginally longer when measured from the point of shoulder to the buttocks than the height at the withers. Despite their diminutive size, Chihuahuas should appear well-balanced and sturdy, never frail or spindly. The breed carries itself with a confident, self-assured stance that defies its small stature. Shorter bodies are preferred in males, while females may be slightly longer to accommodate for bearing young. The Chihuahua's head is its most distinctive feature, characterized by a well-rounded apple dome skull that may or may not have a molera, which is a soft spot similar to a human baby's fontanelle. The muzzle is moderately short and slightly pointed, forming an approximately 90-degree angle where it meets the skull. The eyes are large, round, full, and set well apart, typically dark or ruby colored, though lighter eyes are acceptable in dogs with lighter coat colors. The ears are large and erect, held at a 45-degree angle when alert, and should be flared at the base and taper to a slightly rounded point. The expression should be saucy and alert. The breed comes in two distinct coat varieties: smooth and long. Smooth coat Chihuahuas have short, glossy, close-lying fur that may have a heavier coat with undercoat, with a ruff on the neck preferred. Long coat Chihuahuas feature soft, flat or slightly wavy hair with an undercoat, plus feathering on the ears, tail, chest, legs, and feet. Both varieties may come in any color, including solid, marked, or splashed patterns, with all colors being equally acceptable. The tail is moderately long, either carried in a sickle curve or in a loop over the back with the tip barely touching the back. The breed moves with a swift, firm, sturdy gait, demonstrating good reach in front and strong drive from behind despite its small size.

The Rat Terrier is a well-muscled, compact American breed that comes in two distinct size varieties recognized by the American Kennel Club. The Miniature variety stands between 10 and 13 inches at the withers, while the Standard variety measures 13 to 18 inches tall. Weight is proportional to height, typically ranging from 10 to 25 pounds depending on the size variety. The breed possesses a sturdy, athletic build with a deep chest, strong shoulders, solid neck, and powerful legs that reflect its heritage as a working farm dog. The body is compact yet substantial, giving the appearance of a dog built for both speed and endurance. The topline is level when standing and moving, contributing to the breed's balanced silhouette. The Rat Terrier's coat is short, smooth, dense, and shiny, lying close to the body and requiring minimal grooming. The breed is always parti-colored, featuring a white base with patches of one or more additional colors. Acceptable colors include black, chocolate, red, apricot, blue, fawn, tan, and lemon, with tan points being common in tricolor patterns. The coat should have a glossy appearance that reflects the dog's overall good health. Seasonal shedding is moderate and can be managed with regular brushing. The skin fits smoothly over the muscular body without excess wrinkling. The head is wedge-shaped when viewed from above, with a moderately broad skull that tapers slightly toward the muzzle. The stop is moderate but distinct. The ears can be carried erect, semi-erect, tipped, or button style, though they should always be alert and mobile when the dog is attentive. Eyes are oval-shaped, set wide apart, and come in various colors that complement the coat, expressing intelligence and alertness. The breed may be born with either a natural bobtail or a full-length tail, both of which are equally acceptable. When present, the tail is carried in an upward curve. One of the Rat Terrier's most distinctive features is its hackney-like gait, characterized by a high-stepping, elegant movement that demonstrates the breed's exceptional agility and athleticism.
