These are the standards that all breeders should do their best to have as breeding
goals. Some standards are required for registration and a complete list of standards
which are required for registration is listed afterwards.

Traits discriminated against, traits which are suggested to be used minimally in
breeding the sheep, are a fault and are not a disqualification and animals exhibiting
faults in one area or another are still able to be registered. An animal displaying a trait
that is listed as a disqualification is NOT able to be registered or recorded. Sheep
which do not exhibit the requirements for registrations are considered to be
disqualified and not eligible for registration.

The General Character and Appearance of the Sheep represented by the United
Horned Hair Sheep Association, Inc., should be one of a noble animal. The sheep
should look like an athlete with a lean, sleek form. The sheep are not purely a meat
breed but are more for multiple markets
(Click Here for more information about
multiple markets) and may not necessarily weigh nor exhibit the deep and heavy
muscling of sheep which are considered purely meat breeds.

Should be well balanced and proportional to the body and held high when the sheep
is alerted. Ewes should have a more feminine face and features than the rams.

The back of the head of mature rams may display a slight to extreme rounded hump
behind the horn base. This is part of the rams’ physical frame which helps cushion the
brain during any sparring.

Young lambs typically have a straight profile.

As ewes age, some may display a slight roman nose (elevated area on the nose
bridge seen when viewed from the side profile) while many will maintain the straight

As the rams age, a slight to moderate roman nose (elevated area on the nose bridge
seen when viewed from the side profile) may be displayed. One may note a bigger
elevation on the nose bridge during times association with breeding cycles or during
an increase in sparring activity among rams.

Nose pads and lips must be pink.  Black spotting or areas on the nose pads or lips or
solid black colored nose pads are a disqualification from registration. SEE PICTURES

White sheep which have solid black noses and lips may be registered as an American
Dall.   If you are interested in registering a sheep which otherwise meets all the breed
registraton requirements for a Texas Dall, except for having black noses and or lips
and or an excess of pigmentation (black color) around the eye, please contact the
Secretary, at

The Texas Dall Sheep is considered a hair or shedding sheep. These sheep actually
have two coats: a hair type coat and usually a more wooly undercoat. The undercoat
may resemble a thicker hair to a more wool type look and texture. This undercoat
grows during cool weather and will naturally shed off when warmer weather arrives.

In colder climates, some sheep may exhibit a 3 inch or more full winter undercoat;
however, the undercoat should completely shed off without shearing when warm
weather arrives with the exceptions of lambs and some yearlings.

The ability of the sheep to grow and shed the undercoat, may lead to only partial
shedding for a time in various climates. A complete shedding generally occurs by May,
June or early July. The exact time for a complete and natural shedding depends on
the climate. Lambs and some yearlings may not shed totally till the next year.

Texas Dall sheep with possible close Mouflon breed influence, may have a slight
shedding of coarse guard hairs in the fall, dependent of the climate.

The complete and natural shedding ability is important in maintaining ease of care and
a lack of such shedding may be indicative of parent breeds in the background that are
not desirable or of having wool parent breeds in the recent background.

Texas Dall Sheep should have a completely white coat color. To be registered, the
sheep must not have any other color than white in the coat.  There should be no
visible reddish or fawn spots or hairs within the coat.  

With white coats, the skin of Texas Dalls should not show any pigmentation either.  
However, very limited light brown pigmentation on the lower or upper eyelid margins,
especially on aged Texas Dalls, is acceptable for registration  purposes.

Ears should be parallel to the ground or at slightly higher angles. A very slight angle
below parallel to the ground is noticeable at times; however, the ears should become
parallel to the ground or higher when on alert. SEE PICTURE TO THE RIGHT

While at birth, lambs may display droopy ears, especially those who are part of a
multiple birth; however, the ear(s) should straighten up within a few days. Otherwise,
ears must not droop enough to be considered floppy. Such ears would tend to
indicate cross-breeding in the background of the sheep.  Naturally occurring (not due
to injury or other difficulties) droopy ears are a disqualification for registration.

Ears generally should come to a slight point at the tip and not be completely rounded
in shape. Elf ears (ears with external cartilage which is generally 1/2 inch to 3 inches
in length and exhibiting a more v-shaped ear) and Gopher ears (ears without visible
extenal cartilage or with less than 1/2 inch) are acceptable. Natural ears may vary in
length but are generally in the range of 3 - 4 inches. Abbreviations used within the
registry are as such: E indicating Elf Ears, G indicating Gopher Ears, and N indicating

Eyes should be bright and alert and must be free from genetic eyelid defects such as

The color of the eyes vary from dark brown, golden brown to amber.

It is preferred for no pigmentation around the eyes to exist; however, very limited light
brown pigmentation on the lower eyelid margin or top eyelid margin is allowed.


Incisor teeth should meet the dental pad. A severe and distinct space between the
incisor teeth and the dental pad is a disqualification.

Sheep should not have an extreme overbite (parrot mouth) or underbite (monkey jaw).


CLICK HERE to learn how to estimate the age of your sheep by looking at the teeth!

Neck should continue from the head and gradually lead into the shoulders and be
gracefully held when sheep are alert.

A ewe’s neck will be graceful and proportional in size based on the ewe‘s overall frame.

A ram’s neck will be thicker and more muscular than a ewe‘s neck in appearance and
to the touch. During the Fall or cooler weather, rams may display an increase in hair
and undercoat growth around the neck area which will make the neck look much

Mature rams will display a mane in the winter. Some rams will shed the mane
completely in the summer while others will retain the mane. Some ewes may also
exhibit a short mane.

A ram’s mane may be varied in length from short to long, some even almost touching
the ground when in full winter coat. Some manes may be much shorter and hang just
a couple of inches below the bottom line of the chest. A ram with no mane at any time
is a severe fault and is discriminated against.

The shoulders should be developed and muscled proportionally to the size of the
sheep. They should flow into the ribs (well laid into the ribs).

The withers (area between the shoulder blades along the top line) may be elevated
with rams exhibiting a more pronounced and higher elevated wither. Some sheep may
have a completely straight topline and no elevation at the withers.

The width of the chest of most Texas Dall Sheep will be narrow to moderate with a
more athletic look - proportional to the size of the sheep.

The width of the front of the sheep should not be greater than the width of the back of
the sheep to facilitate lambing.

Continuing after a smooth transition from straight or elevated withers, the back should
be strong, level and relatively smooth. The Back may tend in width to look lean, sleek,
and athletic.

The back is proportioned to the height of the sheep and is generally not longer than
the height.

Ribs should be well sprung. Abdomen should allow for multiple births and be
proportional for smaller sized ewes; however, Mouflon sheep and high content
Mouflon ewes are primarily shaped and geared toward single births.

The bottom line should not be tucked in at the fore flank nor the rear flank.

The Legs should be sound and proportioned to size of individual sheep. Sheep will
have long athletic legs, usually longer than body height from bottom line to top line.
Rams will generally have thicker legs then ewes.

Legs should have a conformationally correct appearance. Front legs should not be
knock kneed, bowlegged, buck-kneed or calf kneed. Rear Legs should not be cow
hocked, sickle hocked or post legged. Lower Legs on both front and rear legs should
not toe in (angle inward/pigeon toed) or toe out (angle outward/splayfooted) too much.
Pasterns should be strong and correct.


A nice four square stance is desired with legs standing nicely inline with the body of
the sheep.

Continuing from the back, the rump should exhibit a gradually angled slope to the

Size and muscling of rump are proportional to the size of the overall sheep.

The Thigh should be well developed in proportion to the size of the sheep. Texas Dall
Sheep may not display the depth and heavy muscling of some sheep breeds
developed purely for fast gain and high weights (meat) at an early age.

The twist is the junction where the insides of the thighs meet. To compare sheep as
far as meat capability, the measurement of the depth of the twist may be taken. To
measure the depth of the twist, one can place hands at the top of the tail and at the
crotch. This measurement assists especially in judging of pure meat sheep breeds
and shows the depth of muscling in this area. SEE ILLUSTRATION TO LEFT

The Texas Dall Sheep tend toward the depth of the twist being minimal to moderately
deep. The Twist should be muscled proportional to the size and frame of the individual

A ewe’s udder should be well proportioned and relatively symmetrical and have only
two teats. A ewe with more than two teats is discriminated against. The teats should be
free of obvious defects affecting function.

Both Testicles should be uniform and symmetrical, free of obvious deformities.
Testicles should be well sized and the scrotum itself should also be free of obvious


Tail lengths vary.  Shorter tails are preferred.  Tails should not be “round” and should
be more “flat“.         

A tail that is reaching to the hocks is discriminated against.  A tail past the hocks is a
disqualification from registration in the United Horned Hair Sheep Association, Inc.


Hooves should be well formed and kept free of deformities and disease.

Texas Dall Sheep hooves must be white with some darkening as the sheep ages and
with no distinct pigmentation visible.  Distinct Black within the hooves would disqualify
the sheep from being registered (no variegated hooves - SEE PICTURE TO THE

All rams must grow and display horns, however, both polled (hornless) and horned
ewes are acceptable as are ewes with scurs. Some breeders prefer not to have scurs
on their sheep due to scurs being easily knocked off and bleeding that could occur.

Rams with scurs are not eligible for registration. To be registered, ram lambs out of
unregistered parents will need to exhibit horns in submitted registration photographs.

In general, wide horns (horns with plenty of room from the face) are preferred over
horns that may grow close to the face and eventually touch the face. Some flock
owners and breeders prefer horns which are a little closer to face (more heart
shaped) or have tight curls while other flock owners prefer horns which have much
wider areas between the face and the horns or less tight curls (horns almost sticking
straight out).

Filing or training of the horns to prevent horns from touching the face is acceptable
and will not prevent the ram from being registered. However, such activities should
always be disclosed in a honest manner to potential customers.

Horns can be of varying shapes though Texas Dall Sheep seem to display the
Supracervical Horn Type more frequently than other breeds. Some horns may be
wider than others at the “tips“.

Round/Usual Horns
Horns are more round in circumference.  This is the most common actual horn shape.

Ewes’ horns really do not take on shapes as the rams’ horns. They sometimes can be
curved outward or backward. To indicate Horned Ewes in the registry, HE is the
abbreviation used.  SEE PHOTO TO RIGHT

A mature ram’s horn lengths vary based on actual age, individual ram (genetics),
areas of the country (environment and weather), nutrition and health. Growth rate
(rate at which the horns grow) is also dependent upon some of the above factors.
Horns generally slow down during late winter/early spring unless fed to overcome the
slowdown; however, the average overall growth rate for horns for young rams is 1" per
month for the first two years. Some rams may seem to get a good start with quick
growing horns while others horns grow slower but then catch up as the ram matures.

Mature rams usually display 20 - 29 inch length horns to measurements in the 30 - 39
range. A world record is 52 inches long for a Texas Dall ram. Horns generally turn
outward. Bases on mature rams generally run 8 to 9 inches in circumference. Ten
inches in circumference of the base of mature rams’ horns also can be found. Eleven
inches in basal circumference (base measurements) for each horn is exceptional.   

Some breeders will prefer larger base measurements as the horns grow out from the
bases and with larger base measurements, the belief is, the better future opportunity
for growth exists.


While shapes and lengths of the sheep breeds represented by UHHSA, Inc., are
similar, certain breeds prefer certain colors of horns. For the Texas Dall Sheep, horns
must be white with no other colors visible.  There may be some areas of darker color
visible as the color may wash out as the ram ages or may collect dirt; however, distinct
variegated horns are a disqualification.


The average height of the Texas Dall Sheep for the ewes is 20 - 27 inches at the
withers and 21 - 31 inches at the withers for rams.  Individual sheep may be outside of
the range and there is no fault or disqualification for above or below average heights.

Texas Dall Sheep generally run larger in size than the Painted Desert Sheep, and
Mouflon Sheep which are also represented by the United Horned Hair Sheep
Association, Inc.  

The weight of the sheep varies and individual sheep may weigh outside the range.  

Ewes may weigh 60 - 150 lbs with an average of 70 - 100 lbs.  Rams generally weigh
from 75 - 200 pounds with an average of 100 lbs.

Texas Dall Sheep are a naturally shedding, all white hair sheep with Mouflon Sheep
influence in ancestry. All rams must have horns, and the ewes are allowed to have
horns although most ewes are polled. Rams must not exhibit scurs instead of horns,
while ewes with scurs are acceptable.

The first Texas Dalls were first called Snow Sheep and were the results of accidental
matings between Mouflon Ewes and Horned Rambouilet Rams.

The Sheep should not contain, to the best knowledge of the owner, any polled blood
or other types of polled bloodlines, including but not limited to Dorper, Katahdin, and
St. Croix sheep breeds. Horned Ancestry bloodlines accepted are Texas Dall,  
Mouflon, Horned Rambouliet, Merino, or Navajo Churro.  Because of the chance for
spotting, the parent wool breed (Jacob) which may produce spotting in the progeny
should probably not be used.

While the original crosses occurred several decades ago, some breeders may wish to
create new bloodlines using one or more of the parent wool breeds. To be registered,
Texas Dall sheep must consist of 1/8th or less of parent wool breeds and meet all
other breed standards.

Texas Dall Sheep which are directly bred from parent wool lines listed above, must
completely shed and additional pictures showing the completely shed sheep may be
required for registration if the pictures submitted does not clearly show the sheep
shedding or having shed.

Information about any known background of the ancestral breeds should be included
in pedigrees with their percentages of the breeds noted to assist breeders in choosing
bloodlines. If a sheep is unregistered, the animal should be clearly labeled as
unregistered. This information should include any known wool breeds in the bloodlines.

What to do when sheep which are registered as Texas Dall when mated with another
Texas Dall Sheep, produces the occasional fawn spotting or other nonstandard
coloring which does not disappear.  Are these color producers then still considered
Texas Dall Sheep or are the offspring simply expressing a color phase?  For UHHSA
and the Texas Dall Registry Division  purposes at this time, a Texas Dall Sheep will be
defined as an all white sheep which, when bred to all white sheep normally produces
all white sheep and which has no known spotting genetics in the known pedigrees of
the sheep.

While some market opportunities do not require such distinction, for registration and
breeding purposes of a Texas Dall Sheep, production of spotting and color variances
should matter and is highly discriminated against.   Animals displaying nonstandard
coloring are not eligible for registration as a Texas Dall Sheep.  UHHSA and the Texas
Dall Registry expects it’s members to fully disclose any known spotting that exists in
their Texas Dall Flocks and work on minimizing spotting and the chance for spotting or
nonstandard coloring to the best of their abilities.

While each shepherd needs to make decisions on their flock management, it is
strongly suggested that if a registered ram or registered ewe is shown to produce non
standard coloring with different mates, that sheep be removed from the Texas Dall
breeding program.

If Any Sheep are produced which do not meet the color standards for the Texas Dall
Registry, PLEASE consider registering them with the Painted Desert Registry division
of UHHSA if they match the Painted Desert Breed Standard or another division within
UHHSA if they match the division’s Breed Standards.
