American Hairless Terrier
Breed Standards
The first standard listed is the
new 2004 United Kennel Club (UKC) and American Hairless Terrier Association (AHTA) breed standard for the American Hairless Terrier. It is the current standard in use.
The last standard
is the original breed standard for miniature and toy AHT's by the
American Hairless Terrier Association (AHTA) and the American
Hairless Terrier Club (AHTC).
July 26, 2006
- Update to the
UKC standard
According to the AHTA: "The upper height limit was raised from 16 inches to 18 inches for
the AHT UKC Standard. This was done to correct a mistake on the
original AHT standard voted and approved by the AHTA in 2004. This
correction to the AHT standard became effective 7/26/2006."
AMERICAN HAIRLESS
TERRIER
Official U.K.C. Breed Standard 2004
History
The first American
Hairless Terrier, a female named Josephine, was born in 1972, part
of a litter of purebred, coated Rat Terriers. The breeder, Edwin
Scott, began to develop the breed from Josephine's descendants.
Although he never used any dogs but Rat Terriers in his breeding
program, it was always Scott's intention for the hairless dogs to be
a separate breed. However, in 1999, when United Kennel Club
recognized the Rat Terrier, Scott and his fellow breeders agreed to
allow the hairless dogs to enter the UKC registry as Rat Terriers,
hairless variety. Upon separation, all of the hairless Rat Terriers
and all of their coated descendants, products of careful breeding to
the finest coated Rat Terriers, were given the name originally
chosen for the breed by Edwin Scott: American Hairless Terrier.
While it may seem contradictory to have coated dogs in a hairless
breed, it will be necessary for the foreseeable future to continue
to include some Rat Terrier crosses until there are sufficient
hairless dogs to maintain a separate and healthy gene pool.
The American Hairless
Terrier was recognized by the United Kennel Club on January 1, 2004.
General Appearance
The American Hairless
Terrier is a smoothly muscled, active, small-to-medium 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, tipped or button. Both varieties may have a natural
tail carried in an upward curve, or the tail may be docked in dogs
of the coated variety. The American Hairless Terrier comes in a
number of skin colors and patterns (hairless variety) and coat
colors and patterns (coated variety).
Disqualification: A
short-legged dog whose proportions vary significantly from the 10:9
ratio lacks breed type and must be disqualified.
Characteristics
The American Hairless
Terrier is an energetic, alert dog whose curiosity and intelligence
make him easy to train. The ancestors of this breed were bred to
hunt. The lack of coat makes the hairless variety unsuited for
hunting, but both varieties still have a strong hunting instinct and
the coated dogs are fearless, tenacious hunters with seemingly
unlimited energy. The American Hairless Terrier is an exceptionally
friendly companion, getting along well with children, other dogs,
and even cats. American Hairless Terriers enjoy human companionship
immensely and will enthusiastically share any activity with their
owners. The hairless dogs require protection from the sun and winter
cold weather. American Hairless 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 American Hairless
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 American
Hairless 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, moderate in size, and somewhat prominent.
Eye rims match nose pigment.
Hairless Variety: Eyes
may be any color found in the coated variety.
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.
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. Erect ears are
preferred but tipped or button ears are acceptable. 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.
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, smoothly muscled, 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
American Hairless 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. The tails of the coated variety dogs may be docked.
If so, docking should be between the second and third joint of the
tail.
Faults (both
Varieties): Bent tail; ring tail.
Disqualification (both
Varieties): Natural bobtail.
Coat
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
American Hairless 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.
Coated Variety: The
coat is short, dense, and smooth, with a sheen. Whiskers are not
removed.
Serious faults
(Hairless variety): Vellus hair longer than 1mm on a dog over six
months of age.
Disqualifications (both
varieties): Wire or broken coat; long coat.
Color
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.
Coated Variety: The
coated American Hairless Terrier may be solid white, bi-color,
tri-color, sable or brindle, but must always have some white, which
may be of any size and located anywhere on the dog. The white area
may be ticked as long as white predominates. The remaining accepted
colors are: black, tan (ranging from dark tan to very light tan and
from intense dark mahogany red to light red with black nose and
eyerims), chocolate (ranging from dark liver to light chocolate with
self-colored nose and eyerims), blue and blue fawn (with
self-colored nose and eyerims), apricot (ranging from orange to
faded yellow with black nose and eyerims), and lemon (ranging from
orange to faded yellow with self-colored nose and eyerims).
Faults (Coated
variety): Fawn (pale yellowish tan with self-colored nose), cream
(pale yellow to off-white), fallow with black mask (very light
yellowish tan with black mask), and silver (the extreme dilution of
blue).
Disqualifications
(Coated variety): Merle; absence of white; any solid color other
than white.
Disqualification (both
Varieties): Albinism.
Height and Weight
The American Hairless
Terrier ranges in height from 10 to 18 inches tall. [Note: Height
in the standard was updated 7/26/06.]
Faults: Height under or
over allowed range; obesity.
Gait
The American Hairless
Terrier moves with a jaunty air that suggests agility, speed, and
power. American Hairless 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 rat io. Hanging ears. Natural bobtail. Wire or broken
coat. Long coat. Albinism. Merle.
