Our "Questionable" are horses that, for one reason or another, have not been
generally accepted as being duns, yet may be, whether or not they have dun-like
markings.
Introduction:
It's nice when we have "all of the requirements" to declare a horse a dun: a
sharp dorsal stripe, clearly visible leg markings, other (neck, shoulders, ears,
face, back) dun markings, and similarly-marked parents and offspring...and now,
a positive test for the "dun markers"!
But what of those with some of those "requirements" missing? A test is
now available, but sometimes it raises more questions than it answers!
There are many, many horses in the "doubtful area" of dun-like markings:
-
horses with a sharp dorsal stripe but no visible
markings on the legs
-
horses with other markings, when there are no visible
markings on either parent
-
horses with no visible markings, yet which beget those having
them
-
horses born with markings that fade
with age
-
horses with one or many dun markings that belong to breeds wherein dun is
not believed to exist
-
-
horses that are so dark all over that the markings are not completely
discernable as being a darker color, but more of a difference in
texture or nap
-
horses whose markings come and go with the seasons or different ages
-
palominos or offspring of palominos in whose registry dun is a
disqualification
-
extremely light horses where dun markings, if extant, would amount to
"white on white" (see OSO X ["Blue"], just below, or button at right.)
-
horses with dun markings that are also sooty in places (some believe the
two cannot co-exist)
If you have some related pictures you'd like to share, please
send them to the "dungenes" list or to bakostelnik@gmail.com .
Please be sure to explain your pictures' purpose in your email. Otherwise I won't know on which web site or which page to use it, or
regarding what question you're sending it.
Thank you.

Avispado, an Iberian who tests "black" and has a diluted body color and
dun striping. Owned by Linda
McLachlan of New Zealand. He has relatives with similar coloring,
as well.

Newest puzzle! This Morgan mare is
believed to be "only" a brown buckskin. "Everyone says" that she has
none of the known dun carriers in the Morgan breed in her pedigree.
However, she has a stripy smoky black sire, who has a cremello dam, who has
two palomino parents. She has never been tested. Indigo Morgans'

This puzzle has been solved. "Blue" is an APHA/AQHA cremello dun
stallion, now residing in Denmark, who has no visible dun markings.
His sire was said not to have any, either, but that turned out to be a
misunderstanding. Blue has sired dun foals and has dun in his pedigree. More about
him here. (Or use button at right.)

NEW! These pictures were provided by Carolyn Shepard, who is
positive these cannot be dun horses, so they have not been tested. Added to
this page 7/24/2008.
Some foals have temporary or partial "dun markings"
Yet they belong to breeds where the pattern is unheard of in adult
horses!

Arabian, LL Amaretto, registered bay; his owner says he is colored like
a dun. "He was lighter in color as a six year old. He is almost black now so
it may be hard to see his dun factor". Owned by Janet,
Diamond Branch QH's.

Gayle Norman had the honor of presenting us with the first photo we displayed on this page. Here is a black
Arabian mare, who turned out this way one year. Gayle thinks it's
the unusual amount of sunshine & warmth they've had. She says the
stripe is sharp-edged (click small picture to see bigger one) and much
more visible in person.
|
 |
Gayle also sent us this picture of a black Arabian foal who later turned
gray. This begins to address the phenomenon of many horses developing
dun markings as they turn gray.
|

|
This purebred Arabian foal also belongs to Gayle Norman. Many
Arabian foals have strong dun markings at birth, and a few keep them
throughout their lives!

These three pics are of a Morgan stallion who lives in Rising Sun,
IN with Ray Taylor and Linda Scott. He was presented to me as a bay, but he had such a beautiful dorsal stripe I just had to
take these pictures. I should have taken more of his stripe, these don't show it very well. It goes the whole length of his back
and is very sharp-edged.

breeding.

This

by Mary Haas.

Amanda
Boyle's purebred Arabian mare, Wystyrea, who is turning gray. Look
at the leg marking in the picture at left!

Arabian foal, Wellwisher, bred by Katy Bowen-Brazell, with dorsal,
leg , shoulder, and face markings. Dun is unknown in adult Arabian
horses, yet many are born like this. |

Goldie, a Thoroughbred buckskin filly bred by
Julia
Lord in Indiana. Dun is unknown in adult Thoroughbreds.
We are awaiting the disappearance of her dorsal stripe; she still
had it, at age two. She has not been tested.
The pics below are also of Goldie: |

Quite a change, eh? Lends some credibility to the theory that
dun-type markings can be related to sootiness, at least on foals.

This picture is from Hardy Oelke's book,
Born
Survivors on the Eve of Extinction. It's a purebred Lusitano
foal. Some believe this foal grew up to be non-dun, since "there are
no dun Lusitanos"; but that view is fading fast. |

These
photos are from a maturing THOROUGHBRED filly! She's owned by Carolyn
Shepard of Rancho No Robles. Has not been tested. |

"a smoky black colt I had born last year who expressed every dun
factor in the book- and leg bars to die for- who now is so dark it will take
a test to prove/disprove." |
An Over-simplified Overview
Of course, the Sorraia and related breeds/crosses have many, if not all,
undisputed duns.
Portuguese-bred: There are some undisputed duns in the Lusitano
breed. Others are being studied.
Spanish-bred: This list/website recognizes at least one Andalusian dun.
He resides in New Zealand.
In addition to these, it seems that most other Iberian horses with markings
usually accepted as Dun either:
-
are, or may be, turning gray
-
are suspected to be black or smoky black (with one cream gene) and their
markings are at least partially obscured by the dark coloring of the
surrounding areas
Some believe that the gray gene itself is causing the dun markings in the
first case, and that something like nap or hair texture is causing them in the
second case. |
