Spike Dunbar just called me to tell me Dunbar's Gold sired a brindle foal out of a palomino mare. Details and pictures to follow. If you are thinking of breeding to Dunbar's Gold, see his stallion page in the At Stud section.
Denise Charpilloz of Vancouver Washington bought the AQHA filly nicknamed "ginger" in the sales section. She is now named Sharp One, and when old enough, she plans to breed her to one of the brindle stallions. That will make the first full patterned brindle to full patterned brindle cross that I am aware of.
Several magazines in Europe have expressed an interest in writing articles on brindle horses - a Dutch equestrian magazine and a German Quarter Horse journal. Hopefully after people see the articles, we will turn up more reports of brindles in Europe.
I have a son of one of my brindle mares that I suspect is a carrier, although he does not show an obvious pattern himself. I have bred him to my mares, and have produced a brindle, but with so few foals so far, it is difficult to say if the pattern is coming from the mare or from him at this point. However, if it does turn out he is a carrier, it will demonstrate that there are minimal forms of brindle (just as there are minimal forms of Paint), and that horses with a minimal pattern can still pass it on to their offspring.
Many people ask about the genetics of brindle. At this time it appears there are two ways a brindled outward appearance (phenotype) can be produced. One way is mosaicism or chimerism. The other way is from a brindle gene (or possibly multiple brindle genes - similar to how Paint patterns can result from several different genes). There are more detailed articles on each in the archives section (see below).
I want to thank everyone that has sent me reports of brindles they have come across. I am sorry I am so behind in posting updates to the website. I have been working, taking care of my horses, and going back to school (not easy at my age). It hasn't left me much time. I did manage to get out all of the previous articles written to make an archive section.
We have posted previous articles written in an Archive section on another website at Geocities. While I have tried to check the links, some of the links in the actual articles may not work the same as when they were posted here originally.

You may get scripting errors when accessing these pages on Geocities. You can just click the button to continue, because my webpages do not use scripting. This error seems to be caused by the pop-up ad box that Geocities loads.
There is a new registry for brindle horses started by Anita Garza in 1998 called the Brindle and Striped Equine International. She is registering brindle, heavy dun factor, "netting", horses, zebra hybrids, zebras, donkeys, mules, ponies, etc. She says her registry will have a Register of Merit awards program. Contact her for more detailed information at 409-793-4207, e-mail, Anita Garza, 11819 Puska, Needville, Texas, 77461.
Some brindle horses can be registered with the IBHA as "brindle dun". They have had the category "brindle dun" since approximately 1971. Unfortunately they aren't able to produce a list of horses registered as this color since most occurred prior to computer searches being generally available. Visit their website for more information, or contact: (219) 552-1013, International Buckskin Horse Association, PO Box 268, Shelby, IN 46377.
The International Striped Horse Association started by Mary Jagow in 1988 has been closed in March 1999 as per Mary Jagow.
This slideshow was last updated January 1, 2000. To see if new pictures were added since the last time you were here, you may have to "refresh" or "reload" your screen. Remember, these photos in the slideshow are for informational purposes only, in order to educate people on how variations in the Brindle pattern can look. Most of these photos are copyrighted and cannot be reproduced without permission. There is a link at the bottom of the page to a photo that can be printed out and distributed to your friends if you wish. If you have trouble with the slideshow, the pictures can also be viewed through our Table of Brindles. The photos on the table, even though small, take a while to load because they are links to larger photos, and the larger photos are the ones that are being loaded. However, you can scroll down and read the table, and click on the unloaded photo box to jump to that larger picture if you wish. If it shows the photo as being not found, it is one of the photos I haven't completed yet.

Click this type to go to our section of unnamed horses, and click each picture to continue. Please see if you can recognize any of these horses. The first three unnamed photographs were probably taken around 1978 to 1980 by Chuck VanHorn of Cave Creek, Arizona, to make a slideshow presentation demonstrating various colors and markings for the International Buckskin Horse Association. Unfortunately, names of the various horses were not recorded. The next two unnamed photographs were taken of Bavarian Warmbloods in 1989 by Evelyn Simak. If you recognize any of these horses, please contact us.
The Brindle pattern consists of a watery or drippy looking striping (sometimes just partial striping) over the body of an animal. It is more commonly seen in dogs or cattle. In horses, the pattern is extremely rare. Brindle has occurred in such diverse breeds as Arabians, Thoroughbreds, Mustangs, Quarter Horses, Tennessee Walking Horses, German and Bavarian Warmbloods, Russian Horses, Spanish Horses, and also in Donkeys and Mules.
Many people confuse the Brindle pattern with Dun Factor markings (stripe down the back, barring on the legs, and occasional regular-spaced striping down the ribs). At one time, it was thought Brindle was a just a variation of Dun Factor. Indeed, there have been many examples of horses that were probably carrying both Dun Factor and Brindle. However, as can be seen from pictures of numerous Brindles in our slideshow, many do not have any Dun Factor markings whatsoever, indicating the two patterns are probably distinct genetically. Click highlighted type to compare Dun Factor and Brindle.
Brindle horses also have texturing in their coat, similar to that seen in some Appaloosa horses. The pattern seems to be inheritable, especially in terms of coat texturing, but the expression of the darker or more intense pigment to make the pattern visible is highly variable, and even varies with individual horses seasonally / yearly. Sometimes the pattern seems to be composed of dark hair (black or brown), sometimes of white hair (roan or gray).
Information collected since 1990 on Brindle horses is now shedding some light on the Brindle pattern. It now appears there may be two ways in which a Brindle phenotype (outward appearance) can occur. In some horses, the pattern has not been inheritable, pointing to a possible mosaic or chimeric origin, such as seen in tortoiseshell cats. In other horses, the pattern has been shown to be inheritable. However, there could be several genes involved, producing similar patterns (much as pinto/paint spotting can result from several different genes).
The first record of the Brindle Pattern in Horses seems to be by J.A. Lusis, in the publication Genetica vol.23, 1942. In the article on "Striping Patterns in Domestic Horses", he details a Russian cab horse from around the 1800's, that was preserved and put in the Zoological Museum of the Academy of Sciences of the U.S.S.R., in Leningrad. I believe the horse is now in the Natural History Museum in St. Petersburg, Russia. If anyone has connections to do research in Russia, we could use more detailed information on this horse, if it is available in their archives.
The most recent book mentioning the Brindle Pattern is Jeanette Gower's book Horse Colour Explained, 1999, Kangaroo Press, available thru 20 Barcoo Street, East Roseville NSW 2069. Another book is Phil Sponenberg's book on Equine Color Genetics, 1996, Iowa State University Press, Ames, Iowa, 50014. Another good book on genetics, is Ann Bowling's new book Horse Genetics, 1996, CAB International, available thru Oxford University Press, 2001 Evans Rd, Cary, North Carolina, 27513.
