All About MULES!
The Mule is a cross between a donkey stallion (called a jack) and a horse mare. Hinnies are just the
opposite - a stallion horse crossed to a donkey jennet. For all purposes, hinnies and mules are classified and
shown together under the general term Mule. A mule or hinny may be a male (horse mule or horse hinny)
or a female (mare mule or mare hinny). Sometimes horse mules (the males) are called Johns, and the
mares are called Mollies. Both male and female mules have all the correct "parts" but they are sterile and
cannot reproduce. A VERY few (about 1 in 1 million) mare mules have had foals, but these are VERY,
very rare. No male mule has ever sired a foal. SO if you cross a mule to a mule - you get nothing! Mules
and hinnies must be bred by crossing a donkey and horse every time. (Male mules should also be
castrated, since they are sterile. They can become dangerous with too many hormones, so should always
be castrated. You can't show an intact male mule, anyway, and it is useless to keep them a stallion).
Mules ears are usually somewhat smaller than a donkeys, longer but the same shape as the horse parents.
The mule's conformation will be a combination of traits from both parents. The head, hip and legs usually
take after the jack. Mules do not have pronounced arches to the neck, even from breeds such as Arabians
or Warmbloods. A slight arch or straight neck is preferable to a ewe, or upward curved neck.
The mule will have "combination hair", usually a thin forelock, coarse mane hair, and a tail more like the
horse parent. Both mules and donkeys are shown with a variety of hairstyles from clipped to shaved
(roached). Mules may wear their tails "belled" as decoration, left long and full, or clipped at the top to
emphasize the shape of the hip.
Mules try their best to imitate the donkey's bray, but most have a unique sound that is a combination of the
horse's whinny and the grunting of the wind-down of a bray. Most will start out - Whinee.....and
end in "-aw ah aw". Every mule or hinny will have a unique bray.
Mules usually have brown or tan-colored points, where in the donkey the Light Points are a
shade of off-white. Some donkeys and mules do not exhibit any light points at all - this is not usual (due to
a recessive gene) , but is a good identification marker for registration purposes. Old-timers used to call a
dark muzzled mule "blue nosed". Mules can be any of the colors that either horses or donkeys come in,
along with some unique variations of their own.
The only colors mules do NOT come in is true horse pinto (due to the genetic factoring of these colors,
there are some mules who are close to, but not quite, tobiano patterned, and none recorded in overo).
Mules from Appaloosa mares often have extremely loud patterns, with spots enlarging or "skewing" in
variants of the horse appaloosa. Breeders wishing for a mule with four white feet should try a tobiano
mare. The mule will probably have four socks and/or stockings, with the most usual combination being
four white feet and a splash of white on the tail. The genes of the mule seem programmed for the unusual,
and very strange, loud spotted pinto and appaloosa variants are common. In fact, the best way to produce
a spotted mule is to cross a spotted jack to a solid colored mare. The resulting mule may have pinto-like
patches in a variation of the donkey-spot pattern. Appaloosa mares crossed to spotted jacks have often
produced mule foals that appear to be roan-patched pinto, with dark leopard appaloosa spots over the dark
Mules come in every size and shape imaginable. Miniature mules (even to under 36") can be seen all
the way up to 17 hand Percheron draft (by Mammoth Jacks) Mules. The Poitou donkey was used
exclusively for breeding huge draft mules from a breed of draft horse called the Mullasier - the Mule
producer. The build of the mule is a combination of both parents. The head resembles both, the eyes being
more almond-shaped (inherited from the D-shaped eye socket of the donkey). Male mules may have more
prominent brow ridges like those of most donkey jacks. The neck is straight and has little arch, even in
mules from Arab or Warmblood mares. The overall body shape will be dependent on the conformation of
both parents. Due to hybrid vigor, the mule has the possibility of growing taller than either parent.
The rarer Hinnies are often said to be more horselike than the mule, but more often it is impossible to tell
them apart. Hinnies may tend to be slightly smaller, simply because of the fact that most donkeys are
smaller than horses. Mules can be used in exactly the same sports as horses - under saddle, in harness, for
cutting, roping or dressage. In actuality, they have more stamina and can carry more weight than a horse
of equal size. This is due to the hybrid vigor. There is one particular aspect where the mule actually
outshines the horse, and that is high-jumping. Mules have a particular sport all their own called the Coon
Hunter's Jump. It stems from the raccoon hunter moving his saddle and pack mules through the woods.
Wooden or stone fences could be taken down, but wire ones could not. The hunter would flag the fence
with his coat or a blanket, and jump his string of pack mules over one by one. In the showring, mules
jump a single rail standard to increasing heights. The last clean jump is the winner. Mules only 50 inches
tall at the withers have been known to clear jumps of up to 72 inches. These jumps are not from a
galloping approach, like Puissance, but from a standing start inside a marked area. Truly a remarkable feat.
Mules are not really stubborn. They can seem lazy because they will not put themselves in danger.
A horse can be worked until it drops, but not so with a mule. The "stubborn" streak is just the mule's way
of telling humans that things are not right. Mules are very intelligent and it is not a good idea to abuse a
mule. They will do their best for their owner, with the utmost patience.
