HISTORY

The Rat Terrier is an American breed descended from the terriers brought over by English miners and other working class immigrants. These terriers probably included crosses between the Smooth Fox Terrier, the Manchester Terrier and the now extinct white English Terrier. These dogs were used as ratters, and gambling on their prowess in killing rats was a favorite hobby of their owners. Some of these dogs were crossed with Whippets or Italian Greyhounds (for speed) and Beagles (for hunting ability). Eventually, these tough little terriers evolved into today's Rat Terrier. The breed was popularized by President Teddy Roosevelt, who frequently hunted with his Rat Terriers. Many are still used as ratters and squirrel hunters, particularly in the South, where they are sometimes known as "Feists." The hairless variety appeared for the first time in a litter in 1972.

The Rat Terrier was recognized by the United Kennel Club on January 1, 1999.

GENERAL APPEARANCE

The Rat Terrier is a muscular, active, small-to-medium hunting terrier. The preferred ratio of length of body (prosternum to point of buttocks) to height (withers to ground) to is 10:9. The head is broad, slightly domed, wedge-shaped, and proportionate to the size of the body. Ears are V-shaped, set at the outside edges of the skull, and may be erect or button. Both varieties may have a natural tail carried in an upward curve. The Coated variety may have a docked or natural bob tail. The Rat Terrier comes in solid white, other solid colors with markings, and white with a variety of colored patches. The Rat Terrier should be evaluated as a working terrier, and exaggerations or faults should be penalized in proportion to how much they interfere with the dog's ability to work. Honorable scars resulting from field work are not to be penalized.

Disqualification: A short-legged dog whose proportions vary significantly from the 10:9 ratio lacks breed type and must be disqualified.

CHARACTERISTICS

The Rat Terrier is an energetic, alert dog whose curiosity and intelligence make him easy to train. The Rat Terrier has sometimes been described as having a dual personality. He is a fearless, tenacious hunter with seemingly unlimited energy. When he is not hunting, however, the Rat Terrier is an exceptionally friendly companion, getting along well with children, other dogs, and even cats. Rat Terriers enjoy human companionship immensely and will enthusiastically share any activity with their owners. Rat Terriers should not be sparred during conformation judging.

HEAD

The head is proportionate to the size of the body. When viewed from the side, the skull and muzzle are of equal length and joined by a moderate stop. Viewed from the front and the side, the Rat Terrier's head forms a blunt wedge shape.
Fault: Abrupt stop.

SKULL - The skull is broad and slightly domed. It tapers slightly toward the muzzle. The jaws are powerful with well-muscled cheeks.
Serious fault: Apple head.

MUZZLE - The muzzle is well filled-out under the eyes, well-chiseled, and tapers slightly from the stop to the nose. Jaws are powerful and hinged well back allowing the dog to open his mouth wide enough to catch rats and other rodents. Lips are dry and tight with no flews. Lip pigment matches nose pigment.
Fault: Snipey muzzle.

TEETH - The Rat Terrier has a complete set of good-sized, evenly spaced, white teeth. A scissors bite is preferred but a level bite is acceptable.
Faults: Missing teeth; overshot or undershot bite.

NOSE - The nose is black or self-colored.
Faults: Dudley or butterfly nose.

EYES - Eyes are set obliquely and are round, small, and somewhat prominent. Eye rims match nose pigment.
Coated Variety: Eye color ranges from dark brown to amber and corresponds with coat color. Hazel eyes are acceptable in dogs with lighter coat color. Blue or amber eyes are permitted in blue-colored dogs only, but a dark gray eye with gray eye rims is preferred.
Hairless Variety: Eyes may be any acceptable color.
Faults: Bulgy eyes; deep-set eyes; light-colored eyes in a dog with black coat color or black pigment; both eyes not of matching colors; eye with iris containing more than one color; wall or china eye.

EARS - Ears are V-shaped, set at the outside edges of the skull. Matching ears are strongly preferred. Non-matching ear carriage should be penalized to the degree of the variation. Note: Ear carriage may not stabilize until a dog is mature. Dogs under one year of age should not be penalized for variations in ear carriage.
Coated Variety: Ears are either erect, tipped, or button when the dog is alert.
Hairless Variety: Erect ears are preferred but tipped or button ears are acceptable.
Faults: Erect ears with the sides curved inward forming a shape like a tulip petal; rose ears; flying ears; non-matching ear carriages.
Disqualification: Hanging ears.

NECK

The neck is clean, moderately long, muscular, slightly arched, and tapers slightly from the shoulders to the head. The neck blends smoothly into well laid back shoulders.

FOREQUARTERS

Shoulders are smoothly muscled. The shoulder blades are well laid back with the upper tips fairly close together at the withers. The upper arm appears to be equal in length to the shoulder blade and joins it at an apparent right angle. The elbows are close to the body. Viewed from any angle, the forelegs are straight, strong, and sturdy in bone. The pasterns are strong, short, and nearly vertical.

BODY

A properly proportioned Rat Terrier is slightly longer (measured from prosternum to point of buttocks) than tall (measured from the withers to the ground), and length of the front leg (measured from point of elbow to the ground) should approximately equal one-half of the dog's height. Whether the dog is standing or moving, the line of the back is strong and level. The loin is moderately short, slightly arched, and muscular, with moderate tuck-up. The croup is slightly sloping. The ribs extend well back and are well sprung out from the spine, forming a broad, strong back, then curving down and inward to form a deep body. The brisket extends to or just below the elbow. Viewed from the front, the chest between the forelegs is well filled and of moderate width. Viewed from the side, the forechest extends in a shallow oval shape in front of the forelegs.

HINDQUARTERS

The hindquarters are muscular with the length of the upper and lower thighs being approximately equal. The angulation of the hindquarters is in balance with the angulation of the forequarters. The stifles are well-bent, and the hocks are well let down. When the dog is standing, the short, strong rear pasterns are perpendicular to the ground and, viewed from the rear, parallel to one another.

FEET

The feet are compact and slightly oval in shape. The two middle toes are slightly longer than the other toes. Toes may be well split up but not flat or splayed. Front dewclaws may be removed. Rear dewclaws must be removed.
Faults: Flat feet; splayed feet; rear dewclaws present.

TAIL

The tail is set on at the end of the croup. The natural tail is thick at the base and tapers toward the tip. When the dog is alert, the tail is carried in an upward curve. When relaxed, the tail may be carried straight out behind the dog.

Coated Variety: A docked or natural bob tail is preferred, but a natural tail is not a fault. Docking should be between the second and third joint of the tail

Hairless Variety. A natural tail is strongly preferred. A docked or natural bob tail in this variety is a serious fault.

Faults (both Varieties): Bent tail; ring tail.

COAT

Coated Variety: The coat is short, dense, and smooth, with a sheen. Whiskers are not removed. Hairless Variety: Puppies are born with a soft, vestigial down that generally covers the body. This "down" gradually diminishes until age 6 to 8 weeks, by which time the pup should be completely hairless. A mature Rat Terrier, Hairless variety, is free from hair except for whiskers and guard hairs on the muzzle, and eyebrows. Short, very fine (vellus) hair may be present on the body of a mature dog. The skin is smooth and warm to the touch. The Hairless variety may sweat when overheated or stressed, but this is not to be faulted in the ring.

Serious faults: Vellus hair longer than 1mm on a dog over six months of age.
Disqualifications (both varieties): Wire or broken coat; long coat.

COLOR

Coated Variety: The following colors, color patterns, or combination of colors are acceptable without preference: Solid white; tri-colored (white with patches of black and tan); or bi-colored (any combination of black, tan, chocolate, red, orange, lemon, or blue with white), with or without tan or rust "Manchester type" markings on the cheeks and over the eyes. The white on a bi-colored dog may be of any size and located anywhere on the dog. Any white area may be ticked as long as white predominates. The head may be solid colored, or marked with any facial marking, including sable coloration.
Faults: Fawn, cream, or fallow with black mask; silver.
Disqualifications: Brindle; merle; bi-color where neither color is white; any solid color other than white.
Hairless Variety: Any skin color is acceptable. The skin is usually parti-colored with an underlying skin color and freckles or spots of contrasting color. Freckles enlarge with age, and skin color will darken when exposed to the sun.
Disqualification (both Varieties): Albinism.

HEIGHT & WEIGHT

The Rat Terrier is divided into two varieties for conformation exhibition: Miniature and Standard.
Miniature Variety: Not exceeding 13 inches, measured at the withers.
Standard Variety: Over 13 inches but not exceeding 18 inches, measured at the withers.

Weight will vary depending on the size of the individual dog. Rat Terriers are working terriers and should be presented in hard, muscular condition.
Faults: Height over 19 inches; obesity.

GAIT

The Rat Terrier moves with a jaunty air that suggests agility, speed, and power. Rat Terrier gait is smooth and effortless, with good reach of forequarters without any trace of hackney gait. Rear quarters have strong driving power, with hocks fully extending. Viewed from any position, legs turn neither in nor out, nor do feet cross or interfere with each other. As speed increases, feet tend to converge toward center line of balance.

DISQUALIFICATIONS

Unilateral or bilateral cryptorchid. Viciousness or extreme shyness. Unilateral or bilateral deafness. A short-legged dog whose proportions vary significantly from the 10:9 ratio. Hanging ears. Wire or broken coat. Long coat. Albinism. In the Coated variety: Brindle. Merle. Bi-color where neither color is white. Any solid color other than white.
