Information about Sales and Stallion Listings
Note: Listings of Stallions at Stud and Horses, Donkeys, and Mules for Sale are provided for user's convenience and do not imply any endorsement of animals listed. We categorize animals based on photos and the latest information provided by the owners or other sources. As visual inspection of equids for brindle characteristics is not possible in most cases, and as so little is known genetically about the brindle pattern at this time, the category we place an animal in is subject to revision at any time. We may need to re-categorize animals as more information becomes available on either the animal, or on the genetics of the brindle pattern. We can make no warranties or endorsements as to an animal's actual color, breeding, serviceability, soundness, etc. Actual sales price may have changed since the information was originally sent to us. You must contact owners of animals for current prices, verification of information, additional information, or for purchase arrangements.
We define "brindle" as a striping pattern seen in horses, donkeys, and mules which resembles the pattern seen in dogs and cattle that is also referred to as "brindle". As there are other types of striping in equids, you might want to check the section on Brindle Characteristics or the slideshow to familiarize yourself with the pattern we are referring to. Very little is known about the genetics of the brindle pattern in equids at this time. Previously, it was thought to be a random mutation or coat developmental abnormality that was probably not inheritable. However, we have found examples of brindles dating back over 100 years, and we know of brindles that have reproduced the pattern, 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 animals seasonally / yearly. While dogs are known to have partial brindle patterns, we do not know if the partial striping patterns we are seeing in some equids are the result of partial brindling (as with dogs), or are just coat developmental abnormalities, and are thus not inheritable.
We define "from known brindles" as the offspring of brindle horses and donkeys in our files (most of which can be seen in the Slideshow), or of equids that we have determined to be probable brindle carriers. Offspring of such animals will be listed for sale in the "from known brindles" category. Offspring of animals with indeterminate patterns will be listed under the "other breeding" category.
We define "relatives to known brindles" as being the immediate close relatives, such as the sire, dam, full or 1/2 blood siblings (other offspring of the same sire or dam, jack or jennet).
We define "indeterminate patterns" as horses, donkeys, or mules with some sort of streaking or texturing which resembles and could be the result of brindling, but could also be the result of some other phenotypical pattern. For example, we don't know if some streaking we see on the ribs of a dun horse is actually a result of brindle + dun, or is just the result of extensive dun factor markings. For example, some streaking on a brown horse could be the result of brindling, but could also have resulted from dappling breaking up countershading. For example, an animal supposedly has brindling, but the photos do not show it clearly, or were taken at a time of year (usually spring) when even normal colored animals will show variations in haircoat as they shed their winter coats. Animals with indeterminate patterns will be re-categorized when better photos or more information becomes available on them. For example, if the dun horse mentioned above only produced ordinary dun factor horses, and never a horse with brindle characteristics, then he would be re-categorized from indeterminate to non-brindle. Offspring of indeterminate animals will be listed in the "from other breeding" category, unless they happen to be the result of "indeterminate x known brindle", in which case they would be listed with the offspring of "known brindles".
